GENEVA (Reuters) - Operations at a Red Sea port in Yemen used for aid imports have fallen to about a quarter of its capacity, a UN official said on Tuesday, adding it was not certain that a Gaza ceasefire would end attacks between the Iran-backed Houthis and Israel.

Yemen’s Houthi rebels have signaled they will limit their attacks in the Red Sea corridor to only Israeli-affiliated ships as a ceasefire in the Gaza Strip takes hold.

Houthi rebels from Yemen have now released the crew of the Galaxy Leader after holding them hostage for more than a year.

Yemen's Huthi rebels accused Washington on Thursday of designating them a terrorist group for supporting the Palestinian people, their stated motive for months of attacks on Israel and in the Red Sea.

The move will authorize harsher penalties on the Iran-backed group, which has attacked Israel and disrupted global shipping trade in the Red Sea for over a year.

Iran on Thursday condemned as "baseless" a move by U.S. President Donald Trump to re-designate Yemen's Tehran-aligned Houthi movement as a "foreign terrorist organization (FTO)".

Yemen's Houthis have indicated they will restrict their Red Sea attacks to vessels linked with Israel amid a ceasefire in Gaza.

An American destroyer, USS Spruance, shot down six missiles and seven drones during a recent Red Sea combat deployment.

US President Donald Trump makes a first big move against the Yemen’s Houthi rebels. President Trump signed an executive order which will initiate the process to relist the Houthis as a Foreign Terrorist Organisation.
