The death toll from a suicide bombing at a mosque in the southwestern Pakistani city of Quetta rose to 15 on Saturday, officials said.
“Two of the wounded people died overnight in the hospital,” said provincial home minister Zia Langove, adding that six people were still in a critical condition.
Islamic State claimed its suicide bomber carried out the attack to target an Afghan Taliban seminary.
“The US condemns this heinous terrorist attack in a place of worship,” Paul Jones, the US ambassador to Pakistan, said in a statement. “I extend our condolences to the families of those who lost their lives.”
The attack was the second in the city this week, while police said they had foiled another by killing a suicide attacker in Rawalpindi city near Islamabad after he shot and killed two policemen.
The Taliban denied in a statement that some of its members, including a senior commander, were killed.
