A series of bombings in different parts of Pakistan killed 103 people on Thursday, including 69 who died in a sectarian attack on a bustling billiard hall in the southwest city of Quetta, officials said.

The blasts punctuated one of the deadliest days in recent years in Pakistan, where the government faces a bloody insurgency by Taliban militants in the northwest and Baluch militants in the southwest.

The country is also home to many enemies of the U.S. that Washington has frequently targeted with drone attacks. A U.S. missile strike Thursday killed five suspected militants in the seventh such attack in two weeks, Pakistani intelligence officials said.
