Islamic State claimed responsibility for a suicide bombing in Pakistan that killed at least 70 people and wounded more than a hundred on Monday in an attack on mourners gathered at a hospital in Quetta, the group's Amaq news agency reported.
"A martyr from the Islamic State detonated his explosive belt at a gathering of justice ministry employees and Pakistani policemen in the city of Quetta," Amaq said.
The bomber struck as a crowd of mostly lawyers and journalists crammed into the emergency department to accompany the body of a prominent lawyer who had been shot and killed in the city earlier in the day, Faridullah, a reporter who was among the wounded, told Reuters.
Television footage showed scenes of chaos at the hospital in Quetta, with panicked people fleeing through debris as smoke filled the hospital corridors.
Bodies lay strewn across a hospital courtyard shortly after the blast and pools of blood collected as emergency rescuers rushed to identify survivors.
The Pakistani Taliban faction Jamaat-ur-Ahrar has also claimed responsibility for the attack.
