Islamabad, Oct 20 (IANS): A hand grenade attack at a restaurant in Pakistan's Balochistan province has left 20 labourers injured on Thursday, the media reported.
The labourers were dining at the restaurant in the coastal city of Gwadar when unidentified militants hurled hand grenades at them before fleeing the scene, 92 news said.
Most of the injured were from neighbouring Sindh and east Punjab province working on some projects in the city, the report said, adding that the wounded have been rushed to a nearby hospital.
At least five among the injured people are said to be in critical condition.
No group or person has claimed the attack yet. Such attacks in the past have been mostly attributed to nationalist groups who want Baloch people to work in place of Sindhi and Punjabi labourers.
Police cordoned off the area for investigations.
