Russian warplanes bomb ISIS targets, activists say

Moscow claims new airstrikes in Syria hit ISI... 02:30

Syrian anti-government activists said Russian warplanes carried out a third day of airstrikes Friday, possibly hitting targets held by the Islamic State of Iraq and Syria, or ISIS, for the first time.

Russia said its airstrikes in Syria will only intensify and could last four months, reports CBS News correspondent Holly Williams.

2nd Day Of Russian airstrikes in Syria 01:27

Moscow joined the Syrian civil war claiming it would target ISIS, yet many of the Russian airstrikes so far have hit areas well outside of ISIS control.

However, the Britain-based Syrian Observatory for Human Rights reported that Russia conducted air raids on Qaryatain, a predominantly Christian town recently captured by ISIS, late Thursday night.

In northern Syria, Russian war planes have pounded groups linked to al Qaeda, but also so-called moderate rebels, who are supported by the U.S.

One video posted on the Internet appears to show the aftermath of a Russian strike on American-backed opposition fighters.

Syria's deadly civil war is now even more dangerous with both the U.S. and Russia launching airstrikes, but supporting different sides.

Col. Abdul Jabbar al-Akaidi is a rebel commander in Syria's U.S.-backed opposition.

"The Russians are occupiers," he told CBS News. "They're attacking anyone who's fighting against the Syrian regime, but not ISIS."

Yet even as Russian airstrikes target U.S.-backed rebels, Col. al-Akaidi told us he's given up hope that America will intervene.

"I don't think President Obama is sincere," he said. "The Americans let us down, and I don't trust them."

U.S. and Russian officials spoke yesterday in an effort to reduce the risk of an accidental collision in Syrian airspace. Russian President Vladimir Putin will meet in Paris Friday with the leaders of France and Germany, both of whom have called for Russia to stop its airstrikes on Syrian rebels.
