Blast kills six, wounds dozens in Philippine southern city

MANILA (Reuters) - A powerful blast ripped through a crowded popular nightclub in a southern Philippine city late on Friday, killing six people and wounding dozens, police said on Saturday, a reminder of the security challenges despite rising economic growth.

No one has claimed responsibility for the attack and an army spokesman said security forces are looking into a potential motive for the attack, including the possible involvement of communist rebels who are active in the area.
