A group supporting ISIS on Wednesday called for more attacks in Europe over the holidays, posting photos of reindeer and Santa Claus next to armed jihadis. The Nashir Media Foundation, an Islamic State terror group propaganda magazine, encouraged attacks on marketplaces and hospitals, cautioning Muslims to avoid Christian celebrations for fear of being targeted, the SITE Intelligence Group reported. “Their celebrations, gatherings, clubs, markets, theaters, cinemas, malls, and even their hospitals are all perfect targets for you,” the message said. Jihadis will soon “replace their fireworks with explosive belts and devices, and turn their singing and clapping into weeping and wailing,” it said. European authorities are already on high alert after an ISIS-inspired attack in Berlin killed 12 people last week.
