Chemical Weapon, Syrian Uprising | featured news

The United States has evidence that the chemical weapon sarin has been used in Syria on a small scale, Defense Secretary Chuck Hagel said Thursday. But numerous questions remain about the origins of the chemicals and what impact their apparent use could have on the ongoing Syrian civil war and international involvement in it.

Syrian government forces have used chemical weapons - probably nerve gas - in their fight against rebels waging a two-year-old uprising, the Israeli military's top intelligence analyst said on Tuesday.

An inquiry will begin “as soon as practically possible” over allegations that the weapons were used in Aleppo Province, said the Secretary General Ban Ki-moon.

The specter of chemical weapons attacks in the Syrian civil war emerged Tuesday, with the government and rebels each blaming the other for using such munitions.

U.S. and allied intelligence have detected Syrian movement of chemical weapons components in recent days, a senior U.S. defense official said Monday, as the Obama administration again warned the Assad regime against using chemical weapons on Syrian rebels.

President Obama’s warning to Syria that the use of chemical weapons would cross a “red line” for the administration drew criticism Tuesday, with experts saying that the remark could provide President Bashar al-Assad cover to continue battling the opposition with tanks, warplanes and other conventional weaponry.

Russian Foreign Minister Sergei Lavrov warned the West on Tuesday against any unilateral action on Syria after President Barack Obama said U.S. forces could act if the Syrian leader deployed chemical weapons against rebels trying to topple him.

President Obama on Monday threatened military action against Syria if there was evidence that the government of President Bashar al-Assad was moving its stocks of chemical or biological weapons. It was Mr. Obama’s most direct warning of American intervention in Syria, where Mr. Assad’s military is fighting an 18-month-old rebellion.
