Russia Offers $50M for Info in Airline Terror Attack

The Russian Federal Security Service is offering $50 million for information leading to the arrest of those behind the downing of a Russian jetliner over Egypt.

President Vladamir Putin is vowing to hunt down the culprits.

The increased manhunt comes after Russian security leaders confirmed that a homemade bomb placed on board "caused the plane to break up in the air."

"This is not the first time Russia experiences barbaric terrorist crime, usually without any obvious internal or external causes, the way it was with the explosion at the railway station in Volgograd at the end of 2013," Putin said.

The Russian government initially resisted the theory that a bomb caused the plane crash.

Metrojet Flight 9268 crashed over Sinai on October 31. All 224 passenger and crew were killed.
