ISIS threatens terrorist attack at London's Westminster Palace

A photo-montage features London's symbolic burning palace, even calling at the Big Ben explosion, while the rest of the British Parliament is on fire, reports the Daily Mail.

A figure of man with a gun in his hand warns the killing of people who will be present there.

This is not the first time the ISIS has threatened London with terrorist attacks, and it has even occurred that these terrorist attacks actually occur, leading the ISIS to take responsibility.

The description reads: “Only terror. London's attacks start soon”
