Depraved ISIS supporters are calling for attacks against British synagogues and kosher shops — and composing poems predicting that Israeli girls will become “slaves,” according to a report.

The sickos are using social media to urge fanatics to target London’s Jews at the places of worship as they observe the Sabbath, The Sun reported.

Research carried out by Washington-based think-tank the Middle East Media Research Institute uncovered the frightening screeds.

The hateful missives called for the “apes” to be prevented from “attending their places of disbelief” followed by the hashtags #synagogues, #schools and #shops.

Using the online messaging system Telegram, the thugs included a link to Wikipedia that lists British synagogues.

A pro-ISIS channel featured a screenshot from the website of the West London Synagogue.

The caption reads: “‘What are you doing this weekend?’ Hint* how about the zoo and check some monkeys out. #Synagogues #Gatecrash #Events #zoo.”

A bloodied Israeli flag was posted along with a poem reading:

“The sun will shine red between Gaza and Rafa.

“The moon will blacken over the peak at Mt. Hermon.

“Flowers are dead and girls become slaves.

“Loads of soldiers will return to town as corpses.”
