Two NATO warships docked Sunday at the port of Oran on Algeria’s northwest coast for a joint naval drill, the Algerian Defence Ministry said.

The Greek frigate HS Kountouriotis and the Italian patrol ship ITS Montecuccoli are on a visit running from Sunday through Wednesday, it said in a statement.

The Algerian Navy will conduct a PASSEX drill with the vessels to facilitate “the exchange of expertise and the strengthening of cooperation", the ministry added.

PASSEX exercises focus on maritime surveillance. Algeria has previously conducted similar drills with NATO countries in the Mediterranean.

The ships’ commanders and their accompanying delegations paid a courtesy visit to the commander of the main naval base at Mers El Kebir, where talks addressed “ways to advance military cooperation and strengthen bilateral relations,” the statement said.

Mers El Kebir, Algeria’s largest naval base, is located on the coast of Oran. It forms part of the country’s western maritime zone, which covers coastal areas near the border with Morocco.
