More than 90 people have been killed and another 100 injured in a series of blasts in the south-western Pakistani city of Quetta.
At least 81 people were killed and 121 wounded when two suicide bombers blew themselves up at a crowded snooker club in an area of the city dominated by members of the Shiite Muslim community, a senior police officer said.
The first suicide bomber detonated his device inside the club, then 10 minutes later an attacker in a car blew himself up outside the building as police, media workers and rescue teams rushed to the site, officer Mir Zubair Mehmood said.
"Both were suicide attacks, it is confirmed now," he said.
It was the country's deadliest attack since 2011 when twin suicide bombers killed 98 people outside a police training centre in the north-western town of Shabqadar.
Mr Mehmood said the dead included six police officials and a local television camera man. Several rescue workers were also reportedly killed in the attacks.
The snooker club is frequented mostly by Shiites, police said.
There's been no immediate claim of responsibility.
According to the US-based Human Rights Watch, 2012 was the deadliest year on record for Shiites in Pakistan.
The double suicide attack came hours after a bomb ripped through a security forces' vehicle in a crowded part of the city killing 11 people and wounding dozens more, officials said.
"Frontier Corps personnel were the target because the bomb was planted underneath their vehicle," senior police investigator Hamid Shakeel said.
Meanwhile, in the north-western Swat Valley a gas cyclinder blast at a religious gathering killed 22 people and wounded more than 80 others.
The attack has prompted an investigation into possible sabotage.
