Blast at market in Pakistani capital kills at least 20

At least 50 injured, death toll likely to rise

A powerful explosion ripped through a crowded wholesale fruit market in Pakistani capital Islamabad on Wednesday morning, killing at least 20 people and injuring at least 50 more, according to hospital and police officials. The death toll is expected to rise.

There was no claim of responsibility, and the Pakistani Taliban, who have announced a cease-fire until Thursday as they hold peace talks with the government, denied any involvement.
