The Islamic State militant group claimed that they crashed the Russian airplane over Egypt in late October with a bomb made from a soda can.

The group published a photo in the newest edition of its online magazine Dabiq. The photo shows a gold Schweppes soda can and what appears to be a switch to trigger a bomb. But officials cannot verify whether the claim is authentic. Russian officials said on Tuesday a bomb blew up the plane traveling from Sharm el-Sheikh to St. Petersburg. The crash killed 224 people.
