A suicide bomber attacked a crowded Sufi shrine in southern Pakistan on Thursday, killing at least 72 people and wounding dozens more in the deadliest of a wave of bombings across the South Asian nation this week.
Islamic State, the Middle East-based militant group which has a small but increasingly prominent presence in Pakistan, claimed responsibility for the attack, the group's affiliated news agency AMAQ reported.
Senior police officer Shabbir Sethar told Reuters from a local hospital that the death toll was likely to rise.
