UN envoy Martin Griffiths on Thursday expressed deep concerns over recent hostilities in Hodeidah province in western Yemen and called on the warring parties to exercise utmost restraint.
"What we need now is speedy redeployments in accordance with the plan of the Redeployment Coordination Committee," he said, as he ended a four-day trip to the country. During the trip, he held talks with Houthi leaders in Sanaa and paid a visit to Hodeidah.
The warring parties reached an agreement during UN-sponsored peace consultations in Sweden in December for a truce in Hodeidah and exchange of prisoners.
On Wednesday, clashes broke out between forces of the government backed by a Saudi-led coalition and Houthi forces on the outskirts of Hodeidah, 220 kilometers west of the capital Sanaa.
The Houthis have been controlling the city since they ousted the government in late 2014.
Heavy and medium weapons were used in the clashes in which dozens from both sides were killed and injured and the coalition launched airstrikes against the Houthis.
Yemen has been racked by a civil war between the government of internationally recognised president Abdrabbuh Mansur Hadi and the Iran-backed Houthi Group since late 2014. The conflict escalated after the coalition intervened to restore Hadi's government in March 2015, resulting in the world's worst humanitarian crisis.
