DAMASCUS, Syria (AP) -- A U.N. spokesman says a vehicle belonging to a team investigating the Syrian regime's alleged use of chemical weapons has been "deliberately shot at multiple times" by unidentified snipers in Damascus.
Martin Nesirky, who is spokesman for U.N. Secretary-General Ban Ki-moon, says the Monday shooting occurred in the buffer zone area between rebel- and government-controlled territory.
He says the team will return to the area after replacing the vehicle.
The team plans to visit the site in the suburbs of Damascus where an alleged chemical weapon attack occurred last week, reportedly killing hundreds.
Syrian activists and opposition leaders have said that between 322 and 1,300 people were killed in the alleged chemical attack last Wednesday.
The government has denied carrying out a poison attack, but anti-government activists and Doctors Without Borders say that more than 300 people were killed last Wednesday in an artillery barrage by regime forces that included the use of toxic gas.
Some members of Congress are urging swift military action against the Syrian regime if the use of chemical agents in an attack last week is confirmed.
Republican Sen. Bob Corker tells Fox News the U.S. should respond in a "surgical and proportional way."
Democratic Congressman Eliot Engel tells Fox the U.S. must respond "quickly," together with NATO allies, possibly using cruise missile strikes.
