ISLAMABAD: Several labourers were trapped after an explosion happened inside a coal mine in Balochistan on Sunday, reports said.
The labourers were working inside the mine in the Marwar town of Quetta when the explosion happened due to the accumulation of toxic gas inside the mine, the reports added.
Rescue work to retrieve the trapped miners is underway.
Coal mines in the province are infamous for occasional blasts in which scores of people have lost their lives.
Earlier in March, 13 people were killed in two coal mine explosions in the province.
