It's been one of Pakistan's deadliest days. On Thursday, an estimated 115 people were killed in a series of bombings accross the country. A twin explosion in a billiard hall in the city of Quetta killed 81 and injured more than 160, according to police. The second bombing, just ten minutes after the first, killed police, journalists and rescue workers who had arrived on the scene. Militant group Lashkar-e-Jhangvi has claimed responsibility for the attack, which killed mostly minority Sunnis. Another attack in the country targeting soldiers killed 12, and an explosion in a crowded Sunni mosque left 22 dead.
