Pakistan officials say methane gas explosions in a coal mine in southwestern Pakistan have killed at least 6 workers and trapped 45.
Authorities say the blasts happened Sunday in a mine run by the state-owned Pakistan Mineral Development Corporation.
The coal mine is located in the province of Baluchistan, 35 kilometers from Quetta, the provincial capital.
A mining inspector says the presence of methane gas is hampering the rescue operation.
