Two people were killed when security forces opened fire on suspected Maoists at Kalaboni village in West Bengal's West Midnapore district late Sunday night.

A senior police officer said the incident occurred after the joint forces of central paramilitary troopers and state armed police, deployed in the area to flush out the ultras, returned the fire on facing a hail of bullets from the Kalabani jungle, where the securitymen had earlier defused a landmine and rounded up 10 suspected Maoists.
