ISIS has claimed responsibility for the bombing of the Brussels airport and subway, which killed more than 30 people, and is threatening more attacks.
“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.
