Pakistan police say land mine blasts have killed three men and injured five others in insurgency-plagued Baluchistan province.

Police officer Bashir Ahmed says two men were riding a camel early Tuesday in the town of Dera Bugti when it hit a land mine, killing one man and the animal and injuring the second man. In the same area, one man was killed and another injured when their motorcycle hit another land mine.

Police officer Abdul Rasool Bakhsh Rind says another land mine explosion late Monday killed a worker for the state-run power company and injured three others near Baluchistan’s capital of Quetta.

Authorities accuse rebel tribesmen of planting mines to target government forces.
