Russia’s federal security service (FSB) on Tuesday said it would pay $50 million for information about “terrorists” who brought down the plane in Sinai last month with 224 people on board, AFP reports.

The FSB appealed for “help in identifying the terrorists” that exploded a bomb on the A321 plane travelling from Egypt to Russia. “There will be a reward of $50 million for information helping to arrest the criminals,” it said on its website.
