Two dead, 20 wounded in Philippine bus attack

COTABATO: Gunmen opened fire on two buses in the troubled southern Philippines on Friday, killing two passengers and wounding 20 others, police said.

The attack, which police said could be a failed robbery or kidnap attempt, was the latest outbreak of violence in the province of Maguindanao, where a local political clan was accused of murdering 57 people in 2009.

The passenger buses were shot at when they sped past gunmen in military-style uniforms who had tried to flag them down along an isolated stretch of highway, said regional police chief Felicisimo Khu.

Veronica Cruz, one of 22 people treated for gunshot wounds at a local hospital, said the driver in her bus thought the armed men were robbers and chose to run the blockade. The other vehicle followed suit.

"The driver noticed there were armed men on the road but they had no signs saying that they were police and army. They had boulders and tree trunks on the road so he suspected that it was a robbery," she recalled.

The drivers raced to a hospital so the wounded could be treated, but police said two of the 22 casualties were later pronounced dead. (AFP)
