Guwahati, Sep 29 (IANS) Five people were injured when suspected United Liberation Front of Asom (ULFA) rebels hurled a grenade at a crowded market place in Tinsukia town in eastern Assam Friday.

The blast took place just after dusk at Tinsukia, 550 km east from here, district magistrate A.K. Absar Hazarika said.

This is the second attack in the district after the central government called off a six-week-old ceasefire Sunday and resumed military operations against the rebel group.

Seven people were injured including two paramilitary personnel in a blast in the refinery town of Digboi in Tinsukia district Thursday.
