Russia bombs ISIS sites in Syria: Reports

The attacks may have included sea-launched cruise missiles and long-range bombers, the official said on condition of anonymity. Russia gave the United States advanced warning of the attacks, the official said.

The announcement came after President Vladimir Putin vowed vengeance as Moscow confirmed that it was a bomb which brought down a Russian passenger jet over Egypt last month, killing all 224 people on board.

The Russian passenger plane that crashed in Egypt on October 31 was brought down by a homemade bomb placed on board in a “terrorist” act, the head of Russia’s FSB security service told President Vladimir Putin on Tuesday.

Putin vowed to hunt down those responsible for the attack. “There’s no statute of limitations for this, we need to know all of their names,” Putin said. “We’re going to look for them everywhere wherever they are hiding. We will find them in any place on Earth and punish them.”

ISIS has claimed responsibility for bringing the Russian plane down in written statements, as well as video and audio messages posted on the Internet following the crash. It said the attack was retaliation for Russia’s air campaign against ISIS - and other groups - in Syria, where Moscow wants to preserve the rule of President Bashar Assad.

ISIS has also claimed responsibility for Friday attacks in Paris that killed 129 people and wounded 350 others.
