EL-ARISH, Egypt (Ma'an) -- Egyptian authorities seized one ton of explosives en-route to the Sinai peninsula on Sunday, security officials said.

Egyptian security officials searched a car driving from Cairo towards Sinai, and found one ton of explosives hidden inside.

The contents were seized and the driver taken for questioning.

On Friday, Egypt seized two tons of explosives being transported from Cairo to the restive Sinai peninsula. Police received a tip-off that smugglers were taking the cargo through the Ahmad Hamdi tunnel under the Suez canal.

The driver told police he was taking the shipment to a smuggler in Ras Sudr, on the west shore of the Sinai.

In January, Egypt seized six anti-aircraft and anti-tank rockets in the Sinai peninsula.

Egyptian security forces have waged a security campaign in the desert Sinai region to reign in militant groups, after 16 Egyptian border guards were killed in an attack on their post in August.
