“We vow to bring dark days to the crusader nations that have allied themselves against the Islamic State,” ISIS said in a statement, the Independent reports. “And what awaits you will be even harsher, even more bitter.”
The terrorist group said the same thing after the Paris attack in November, which killed 130 people, stating that it was just “the beginning of a storm.”
On a popular web forum for ISIS members, a poll was published asking, “What will be the color of the Eiffel Tower in the next attacks?” Vocativ reports.
The question is a colorful way of asking which country ISIS should strike next. The Eiffel Tower was lit up with the colors of the French flag after the Paris attacks, and with the colors of the Belgian flag after the Brussels bombing.
Twenty users voted in the poll, with nine voting for the United Kingdom, six for Russia, and three for the United States.
ISIS has made videotaped threats to the United Kingdom and the United States in English, for airstrikes in Syria that have targeted ISIS. ISIS has also made videos of executions of people who allegedly spied against the terrorist group.
