叙利亚活动人士指责政府再次使用化学武器

Syrian activists say at least 100 people have been killed in a government offensive near the capital, Damascus, where forces loyal to President Bashar al-Assad are alleged to have used chemical weapons.
 
Syria quickly denied allegations of a chemical attack.  State media reported military activity in the area, saying that government forces had killed "terrorists" - a term used to refer to rebels opposed to Mr. Assad.
 
The Britain-based Syrian Observatory for Human Rights said the military fired rockets at sites in Eastern Ghouta and Western Ghouta.  It cited activists in the area who said "poisonous gasses" were used.
 
Britian and the Arab League have called on Syria to allow U.N. invesigators already in the country to examine sites of the alleged chemical attacks.
 
British Foreign Secretary William Hague said he was "deeply concerned" about the reported chemical attacks, and said if proven true, they represent a "shocking escalation."  He said Britain will refer the matter to the U.N. Security Council.
 
The violence comes as United Nations chemical weapons inspectors carry out a two-week mission in Syria to investigate earlier incidents in which the Syrian government and rebels accused each other of carrying out chemical attacks
