Riyadh: Two Indians and a Saudi policeman were injured when unidentified gunmen opened fire at a security patrol in Saudi Arabia's troubled Shia-dominated Qatif region in the east, the Interior Ministry said on Wednesday.

A traffic patrol at Alkhwaildieh district in Qatif came under 'heavy fire from a farming area', a spokesman of the Ministry said. The firing that occurred last evening wounded two Indian passers-by and a policeman.
