ISIS Celebrates St. Petersburg Metro Blast That Killed 10

It doesn’t mean they are directly responsible of course. From Vocative. 

Motivations behind the attacks were not made immediately clear

ISIS supporters are celebrating two explosions on St. Petersburg subways that have killed at least 10 people and injured at least 20, according to Russian media reports.

“We ask Allah to bless the operation by the lions of the Caliphate, we ask Allah to kill the Crusaders,” said an ISIS supporter from the terror group’s al-Minbar forum. Others celebrated by saying that the Monday bombs made for “a metro to hell for the worshipers of the Cross” and claimed that the attacks, which are still under investigation, were a revenge against Russia’s acts in Syria.

“Russia should drink from the same cup and taste from what the Muslims in Syria have tasted,” said one user, promising that “the next will be worse and more bitter, you worshipers of the Cross.”
