Yemen’s Iran-backed Houthi movement has released the crew of a cargo ship more than a year after its fighters hijacked the vessel in the Red Sea, as part of its campaign of attacks in support of Hamas in its war against Israel.

Prisoner releases have been seen as a bid to jump-start talks to end Yemen's war, which began when Houthi rebels seized the capital, Sanaa, in 2014.

Houthi, said the Iran-aligned group will monitor the implementation of a ceasefire deal between Israel and Hamas and will continue its attacks on ships in the Red Sea if it is breached.
