The aircraft carrier FS Charles De Gaulle and three other French vessels participating in the war against Daesh (Islamic State) are being resupplied by US forces in the Persian Gulf nation of Bahrain, the US Navy said in a press release on Friday.

“It’s easier to work with the US Navy” because the ships are unable “to make port calls at our usual ports,” said French Navy Lt. Guillaume Florczyka, who oversaw the resupply.

The deployment of the Charles De Gaulle in early November took on added significance as it came a week after the massacre of 130 people in Paris by terrorists affiliated with Daesh.

The port call included three other French ships, the air defense destroyer Chevalier Paul, anti-submarine frigate La Motte-Picquet and command and supply ship Marne.

This visit came less than two weeks after the US Defense Secretary Ashton Carter visited the Charles De Gaulle at sea.
