Officials blame Taliban militants for planting the IEDs in the district that has been the scene of heavy armed clashes earlier this year.
More than 1 690 civilians were killed and over 3 430 others injured in conflict-related incidents in the first half of the year in the war-torn country according to figures released by the UN mission in the country.
