At least 22 people have been killed in a suicide bomb attack in the Pakistani city of Lahore. The victims were mainly riot police.
The bomber set off a device packed with ball bearings when police stopped him outside the court.
Up to 60 people, many of them police officers, were rushed to hospital after the explosion in the city's main commercial district.
Six police are critically wounded and 35 have minor injuries.
Police said the head of the suspected suicide bomber had been found about 100m from the blast site, which was littered with the dead and wounded.
The blast ripped through a busy square in front of the Lahore High Court as the riot police were gathering ahead of a protest by lawyers against the rule of President Pervez Musharraf.
The incident comes two weeks to the day after the assassination of opposition leader Benazir Bhutto in a gun and suicide bomb attack.
More than 800 people were killed in militant attacks in Pakistan last year, making 2007 the deadliest in the country's history.
