A suicide blast claimed by the Islamic State group (IS) at a Shiite mosque in Islamabad killed at least 31 people on Friday, with 169 more wounded in the deadliest attack in Pakistan's capital since the 2008 Marriott hotel bombing. The attack was the deadliest in the Pakistani capital since September 2008, when 60 people were killed in a suicide truck bomb blast that destroyed part of the five-star Marriott hotel.
