Islamic State militants have threatened an attack on Rome – with militants promising to throw homosexuals off the Leaning Tower of “Pizza”.

A militant-run IS Twitter account made the threat on Saturday, writing: “#We_Are_Coming_O_Rome, we will conquer and establish the justice of #shariah. We will use your leaning tower of pizza to throw off homosexual

“#We_Are_Coming_O_Rome, we are coming with slaughter.”

The group were seemingly unaware both that they had misspelled “Leaning Tower of Pisa”, and that the tower is actually located in the town of Pisa, nearly 200 miles from Rome.

Rather than succumb to the threats, a number of Rome residents are instead giving the group travel advice, given the city’s notoriously poor transport network.

The threats are the latest in a string that the group has made against Italy – which could be vulnerable to insurgents crossing illegally from Libya.

The country is thought to be deploying extra security to ward off any potential attackers.

Islamic State has previously released footage of what it claims is the execution of gay men in its conquered territories.
