United Nations Mission to Investigate Allegations of the Use of Chemical Weapons

in the Syrian Arab Republic

Report on the Alleged Use of Chemical Weapons in the Ghouta Area of Damascus

on 21 August 2013

Note by the Secretary-General

1.In transmitting simultaneously to the Security Council and the General Assembly the

report on the incident which took place on 21 August 2013 in the Ghouta area of

Damascus (see annex), the Secretary-General expresses his profound shock and regret atthe conclusion that chemical weapons were used on a relatively large scale, resulting in

numerous casualties, particularly among civilians and including many children. TheSecretary-General condemns in the strongest possible terms the use of chemical weapons

and believes that this act is a war crime and grave violation of the 1925 Protocol for the

Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare and other relevant rules of customary international

law. The international community has a moral responsibility to hold accountable those

responsible and for ensuring that chemical weapons can never re-emerge as an instrumentof warfare.

2.The Secretary-General wishes to express his deep appreciation to the Head andmembers of the Mission, including the dedicated teams of experts from the Organisation

for the Prohibition of Chemical Weapons and the World Health Organization. The

Secretary-General is grateful for the support provided by Member States. The Secretary-

General counts on the continued support of all concerned until the Mission completes itsinvestigation into all other allegations and submits its final report.

3.The accession of the Syrian Arab Republic on 14 September 2013 to the Convention on

the Prohibition of the Development, Production, Stockpiling and Use of Chemical

Weapons and on their Destruction is a welcome development. As depositary of theConvention, the Secretary-General has long called for its universality. The Secretary-

General welcomes the agreement reached on 14 September 2013 between the Russian

Federation and the United States of America on a framework for the elimination of chemical weapons in the Syrian Arab Republic. He hopes that the Executive Council of the Organisation for the Prohibition of Chemical Weapons and the United Nations

Security Council quickly move to consider and implement this proposal, which is aimed

at expediting the fufillment of the obligations of the Syrian Arab Republic under theConvention. The Secretary-General calls upon the Syrian Arab Republic to implement



5.Where there are allegations of the use of chemical weapons, however, the international

community looks to the United Nations for an impartial and objective determination

whether, and to what extent, such allegations can be substantiated. It is imperativetherefore that the authority extended to the Secretary-General by the General Assembly

(A/RES/42/37 C) and endorsed by the Security Council (S/RES/620 (1988)) continues tobe respected and that the mechanism related thereto continues to be strengthened. The

Secretary-General believes that an effective mechanism to investigate allegations of the

use of chemical weapons can serve as an important deterrent against their employment.



fnformattion concerning bio -medic al sam ples:

26. B lo od, uri ne and ha ir sam ples. w ere withdrawn from 34 of the 36 patients selected by th e

M ission who had si gns of intoxication. The posi tive blo od and urine specim ens provid e

defin itive: evidence of exposure to Sar in by alm ost all of he survivors assessed by the

M ission. These resu lts are corrobora te d by the clinical ass essments , whkh docum ente d

sym ptom s and sig ns th at a re cons istent w ith nerve agent exposure , in cluding shortn ess ofbreath , eye ir ritation , excessiv e salivation , convuls ions , confusio n/disori entati on, and miosis.

The tl ndings of th e cli nical assessm ents w ere consistent w ith in formation derived from bo th

th e interv iews with clin icians a nd th e review ofm edical records, w hich each re porte dsym pto m s and signs consi stent w ith nerv e agent exposu re . T he re su lts of he biomedical

sample s are disc ussed in A ppendix 4 and di sp layed in A ppendix 7.

Conclusions

27. On the basis of th e evidence obtain ed duri ng our investig ation ofthe G houta in cident,

th e concllus ion is th at, on 21 A ugust 2013 , chem ical w eapons have been used in the ongoing

confl ic t betw een the parties in th e Syrian Arab Republic, also against civ ilians, includin g

chi ldren , on a rela tive ly large sc ale .

28. In particular, the environm en tal , chem ic al and m edical sam ple s we hav e co llected

provide c lear and convin c ing evidence that su rface-t o-surfa ce ro ckets conta ining the nerve

agen t S arin w ere us ed in Ein Tarma, M oadam iyah and Z am alka

inthe G hou ta area of D am ascus .

29. The facts su pporti ng th is conclusion are:

• Im pacted and explo ded su rface-to-surface rockets, capable to carry a chem ic al

payload, were found to contain Sari n .

• Close to th e ro cket im pact si te s, in the ar ea w here patients wer e affected, the

environm ent was fo und to be contam inated by Sarin.

• O ver fifty in terviews given by survivors and health care w ork ers provided am ple

corroboration of the m edical and sc ientific results.

of surviv ors were treated on an outpatient bas is: others required adm ission, with som e sti llin patients at th e tim e of he field visit: oth ers were tran sferr ed to oth er health facilities for a

higher le,ve l of care.

Medical records. The eight m edical re cords from Zam alka Hosp ital were re viewed for

de mographic s, clinical prese ntation, and treatmen t. All cases were m ale , with an avera ge age

of 27 years (range 18 - 50 years) . The most com m on symptoms and signs docum ented

in cluded shortn ess of breath / labored breathing (87.5 %), blurred vision (7 5% ), vomiting

(6 2.5%), mj osis (50% ), and he adache (50 % ). A ll patients receiv ed atr opine e a t m ealthough dosage s were not consist ently re corded . T he other m a in treatments reported

inc luded hydrocortisone (87.5% ) and oxygen (3 7.5% ). A gain , dos ages were not consistently

recorded.

Conclu sion. The po sitive blood and urine spec im en s pro vide definitiv e ev idence of exposure

to Sarin by a larg e proportion of th e survivors assessed by the investigatio n Mission. These

re sult s are corrobora te d by the clinical assessm ents , w hic h documented sym ptoms and signs

th at are consistent with nerve agent exposure , in cluding shortn ess of breath, eye ir rit ation,

excessive sa livation, convuls ions, confusion/disorientation , and miosis. The fin dings of th eclinica l assessments were consistent with in form ation derived from both th e int erview s with

clinicians: and the review of m edical records, which ea ch re ported symptom s and signs

consis tent with ne rv e agent exposure.

Observattions and assessments fr om the Z am alka/Ein Tarma findings:

One team mov ed to the location ofan alleged munition im pact located on the roof of a five

story building, the second team moved to another a lleged im pact poin t lo cated in a nearby

open field.

The two teams worked in parallel and identified th e same type ofmunition at both si tes. T he

munition had features noted as being consis tent with thatof

an unguided rocket. All measurements and dimensions are the result of both team findings . Some rocket parts

were deformed on im pac t a nd the m easurements should be considered as best est imate s.

Based on the orientation of he impact cra ters, orientation of certain surviving munition

in a room below. The suspected front plate of

the warhead and other parts suspected of being

the warhead casing were found in front of the

first wall and not in the lower room.

Additionally, they did not exhibit signs of

significant deformation or damage due to kinetic

impact. Based on the found evidence; there is

an indication that the rocket warhead appeared

to function prior to impacting on the roof,

releasing its contents and depositing the

discovered fragments before travelling through

the structure to its terminal location. Apart from

the rocket motor and the front central tube with

the base plate, no other munition fragments were

found in the lower room.

holes around the outline. It's unclear what

part(s) are attached through these holes.



Impact S:ite Number 1

T he m unit ion linked to th is im pact s ite, by o bserved and m easured characteristics,

in dicat ively m atches one of th e variants of the M l 4 artillery rocket , w ith e ither an original or

an im provised w arhead (not observed at the im pact site). In the final s tage of th is trajectory,

the projectile bi t and pierc ed through a vegetal screen existing over one of th e ad ja cent w alls ,

before impacting the ground producin g a sha llow crater.

T he line linking the cra ter and th e piercing in the vegeta l screen can be conclusively

establi shed and has a bearing of 35 degrees. T h is line represents an inve rse azimuth to the

original t:Jrajectory of the rocket, that is to say, the original trc:tiectory of th e projectile, as it hit

th e gro und, had an azim uth of215 degrees.

Im pact Si tte Number 2 is lo ca ted 65 meters aw ay from num ber 1 and w it h an azim uth of 214

degrees. Both re lative positio ns are fully congruent w ith the di spersion pat tern commo nly

associated w ith rockets launch ed from a s in g le, m ulti-barrel, launch er.

Impact S ite N umber 4

T he m uni t ion rela ted to this im pact s ite by observed and m easured cha racteri s tic s indic atively

matches a 330 rom caliber , a rtillery rocket. T he pro je ctil e, in the last stage of ts trajectory, hi t
