A suicide bomber targeted a police official in Pakistan's financial capital Karachi on Thursday, wounding at least six people near a bank, police said.
"The attack was against me. I was moving with my squad in Malir Halt district when the explosion took place. I am unhurt, but some of my men have been injured," Rao Anwar, a senior police official, told AFP.
He claimed to have been threatened for a month by "unknown terrorists".
Karachi is Pakistan's largest city and its port has been a lifeline for US troops fighting the Taliban in landlocked Afghanistan, though Pakistan shut down the supply lines last November when US air strikes killed 24 soldiers.
"It was a suicide attack," police official Tahir Naveed told AFP.
"The attacker was killed in the blast and the body in hospital is suspected to be his," he added. "Six people were wounded."
The bomber struck near a bank in a garrison area of the sprawling city, which is home to 18 million people.
This week, Pakistan's human rights commission said ethnic, sectarian and politically linked violence had killed at least 300 people so far this year in Karachi, where migration has turned the city into a melting pot of different people.
The last bomb attack in the city killed three soldiers on December 9.
