At least 30 killed in explosion on Pakistani-Indian border - source

LAHORE Pakistan (Reuters) - At least 30 people were killed in an explosion near the Pakistani-Indian border on Sunday after a daily ceremony at the Wagah border crossing, an intelligence source told Reuters. Media reports said the explosion was caused by a gas cylinder but the source said authorities were checking suggestions it might have been a suicide attack. Every day before sunset soldiers from Pakistan and India gather at the crossing, usually drawing big crowds on both sides, to simultaneously lower the two nations' flags.
