Egypt’s army killed six terrorists and arrested another in central Sinai, the army’s spokesman said Saturday in a statement on his official Facebook page.

The army also destroyed a workshop for manufacturing explosive materials and a number of motorbikes, the statement added.

The army’s border guards also found and destroyed an underground warehouse that stored four tons of narcotics ready for distribution.

Egypt’s army and police forces have been waging a war over the past three years against an Islamist militant insurgency in North Sinai. Hundreds of security personnel and militants have been killed in the violence.
