The Eiffel Tower will turn its lights out on Thursday as a mark of respect for the victims of deadly twin attacks in Tehran, which were claimed by the Islamic State group. 

"Tonight, at midnight, the Eiffel Tower will turn off its lights in homage to the victims of the attacks in Tehran. Paris and Parisians stand in solidarity" with the victims, Paris mayor Anne Hidalgo said on Twitter. 

Wednesday's attacks at Tehran's parliament complex and the shrine of revolutionary leader Ayatollah Ruhollah Khomeini killed 17 people and wounded more than 50.
