ISLAMABAD (Reuters) - A bomb exploded in a crowded market on the outskirts of the Pakistani capital, Islamabad, on Wednesday, killing 20 people and injuring about 70 in the deadliest attack in the city in years.

The blast followed weeks of preliminary talks with the main Islamist militant grouping battling the state, the Pakistani Taliban, who last week extended a ceasefire until April 10.
