Egyptian security and naval forces have seized a large shipment of drugs worth more than LE 2 billion (approximately $115 million) aboard a ship off the Red Sea coast, the interior ministry said in a statement Thursday.

A "dangerous" gang of seven foreigners and two Egyptians were planning to smuggle two tons of heroin and 99 kilograms of crystal methamphetamine into the country aboard a European-flagged ship.

Naval forces intercepted the ship, arresting its crew of seven foreigners, the ministry said, without specifying their nationalities.

Authorities are still hunting the two Egyptians.

The ministry described the seizure as "one of the biggest blows to drugs smugglers."
