CHAKWAL, Pakistan (Reuters) - A suicide bomber blew himself up at a gathering of minority Shi'ite Muslims in Pakistan on Sunday killing 22 people a day after a deadly suicide attack in the capital, police said.
Pakistan is crucial to U.S. efforts to stabilize neighboring Afghanistan and U.S. President
Barack Obama has said the release of additional U.S. aid to the nuclear-armed country depends on how it tackles terrorism.
The attack in the central city of Chakwal came a day after a pilotless U.S. drone aircraft killed 13 people including militants in the northwest and a suicide bomber killed eight soldiers in Islamabad.
About 2,000 people had gathered at a Shi'ite religious center in Chakwal, about 100 km (60 miles) south of Islamabad, for a ceremony when the bomber struck.
"There was a break in the ceremony and some people were going out and others were coming in when all of a sudden a young man tried to run into the crowd," said witness Amjad Hussain.
"When guards tried to stop him at the gate he blew himself up."
