A French frigate shot down two drones in the Red Sea that were heading towards it from the coast of Yemen, the French military said on Sunday.

"The interception and destruction of these two identified threats" were carried out late Saturday by the frigate Languedoc, which operates in the Red Sea, the general staff said in a press release.

The interceptions happened at 2030 GMT and 2230 GMT, it added, and were 110 km (68 miles) from the Yemeni coast.

Yemen's Iran-backed Huthi rebels on Saturday threatened to attack any vessels heading to Israeli ports unless food and medicine were allowed into the besieged Gaza Strip.

The latest warning comes amid heightened tensions in the Red Sea and surrounding waters following a series of maritime attacks by Huthi rebels since the start of the Israel-Hamas war on 7 October.

In a statement posted on social media, the Huthis said they "will prevent the passage of ships heading to the Zionist entity" if humanitarian aid is not allowed into Hamas-ruled Gaza.

The Huthis have recently attacked ships they claim have direct links to Israel, but their latest threat expands the scope of their targets.

An American destroyer shot down three drones last week while providing assistance to commercial ships in the Red Sea targeted by attacks from Yemen, according to Washington, which denounced "a direct threat" to maritime security.
