At least seven people have been killed by two suicide blasts at a Sufi shrine in the Pakistani city of Karachi, say officials.
Several other people were injured in the explosions at the busy Abdullah Shah Ghazi shrine.
The BBC’s Shoaib Hasan at the scene says crowds of people are outside the shrine awaiting news of loved ones.
Pakistan’s President Asif Ali Zardari said he condemned the incident “in the strongest possible terms”.
Our correspondent says dozens of security force members were at the scene, and there are scenes of mayhem around the shrine.
Police official Mohammad Nasim told the AFP news agency that the number of casualties could rise.
In a statement, Mr Zardari said the blasts had happened on the shrine’s busiest evening of the week, when people gathered to hand out free food to the poor.
He blamed the attacks on “those who want to impose an extremist mindset and lifestyle upon our country” but said the government would not be deterred.
“We remain committed to fighting these murderers and expelling them from our land,” he said.
The explosions appear to be similar to a double suicide attack on another Sufi shrine in Lahore in July.
More than 40 people were killed and nearly 200 injured in the attack on the popular Data Darbar shrine.
