New videos posted online appear to provide further evidence of the suspected recent use of some sort of chemical agent in Syria.

The Israeli news site Ynet on Tuesday compiled several of the videos from Arabic news sources, reportedly documented the after-effects of an alleged chemical attack on the village of Tamana al-Ghab in northern Syria.

In the videos, which TheBlaze is unable to independently authenticate, children at a makeshift medical treatment area are being given oxygen, having their clothes stripped off and their skin washed — typical first aid in the event of exposure to a toxic agent. Adults in videos posted on YouTube by the Syrian Media Center could be seen wearing surgical masks over their mouths, while two were seen with gas masks.

Ynet cited the Middle East news site Al Arabiya, which interviewed opposition sources who said that hundreds were injured, some due to suffocation.

On Monday, State Department spokeswoman Jen Psaki said that the U.S. had “indications” that a toxic chemical — likely chlorine – was used this month in the village of Kafr Zeita.

“We are examining allegations that the government was responsible,” she said. “Obviously there needs to be an investigation of what’s happened here.”

The Associated Press, citing opposition groups, reported last week that a chemical agent was used in Kafr Zeita, a rebel-held village, injuring “scores of people.” Earlier, an Israeli security source asserted that Syrian government forces loyal to President Bashar Assad had used chemical weapons against rebels in a suburb of Damascus.

Both Assad loyalists and rebels trying to unseat the president blamed each other for employing the unconventional weapons.

While chlorine is less toxic than sarin, which United Nations inspectors believe was used in the August attack that prompted threats of U.S. military intervention in Syria, it is still against international law to employ the chemical substance as a weapon.

President Barack Obama dropped the military threat after Assad agreed to hand over his chemical weapons.

“The Assad regime continues to carry out war crimes in its slaughter of innocent men, women and children,” Sen. John McCain said in a statement, according to Reuters. “Its breach of the chemical weapons agreement should surprise no one, and unless the Obama administration is willing to force a price for such behavior, we should only expect more atrocities to come.”
