A bomb blast ripped through a crowded market in eastern Pakistan on Thursday, killing three people and wounding over 20, police said.
"It was a bomb blast," a police spokesman Arif Rana told Reuters, saying a time device rigged to a motorcycle exploded outside a shop in the market.
A nine-year-old boy is among the three dead, he said.
A separatist group based in southwestern Balochistan province claimed responsibility in a text message sent to a Reuters reporter.
