Syria's government is trading accusations with rebel forces over new reports of a gas attack on a village north of Damascus.

Syrian state TV paints a very different picture of the attack, which they say killed two people and wounded more than 100. Al Arabiya reports state media blame the attack on the radical al-Nusra Front and accuses the group of plotting two more attacks on civilian targets.
And discovering the truth behind this attack might prove difficult. A former Syrian chemical weapons chief told Al Jazeera chlorine attacks "can't be easily discovered, even if the monitoring regime arrives 48 hours later."

The New York Times suggests another chemical weapons attack, even after the regime ostensibly surrendered their stockpiles, could have dire implications for the Syrian civil war. "If the government used toxic arms now, that would suggest that it felt it could act with impunity because of international reluctance to punish it militarily."
On ABC's "This Week", U.N. Ambassador Samantha Power told George Stephanopoulos the U.S. was still investigating that attack.
"We will do everything in our power to establish what has happened, and then consider possible steps. ... We weren't just removing for removing's sake, it was to avoid use. So we will have to look at policy options."
Also on Sunday, Syrian forces launched a series of air raids on rebel-held areas. Observer groups say the country's three-year civil war has cost at least 100,000 lives and displaced more than 9 million people.
