Yemeni security officials say fighting has erupted in the key port city of Hodeida, killing at least eight people, including civilians.

A senior Houthi rebel leader in Yemen says his group will not give up the key port city of Hodeida, the focus of months of U.N.-brokered talks with the Saudi-backed government.

Local tribesmen say airstrikes by the Saudi-led coalition fighting Yemen's Houthi rebels have killed 22 people, including children, in the country's north.

Yemeni security officials and eyewitnesses say that fighting has erupted in the key port city of Hodeida, the first significant clashes since warring sides agreed to a U.N.-brokered cease-fire deal in December.

Security officials say Yemen's Shiite rebels and government forces are shelling each other in areas south of Hodeida, straining an already shaky cease-fire in the Red Sea port city.

Yemen's Shiite rebels on Saturday handed over control of the main port in the Red Sea city of Hodeida to the country's navy and coast guard under U.N. supervision, security officials said, in a significant step in the implementation of a deal reached during peace talks in Sweden earlier this month.

A cease-fire went into force early Tuesday in Yemen's Red Sea port of Hodeida after intense fighting between government-allied forces and Shiite rebels erupted shortly before the U.N.-brokered truce took hold in the contested city, Yemeni officials said.

Fighting has erupted between Shiite rebels and forces loyal to Yemen's internationally recognized government near the strategic Red Sea port of Hodeida, leaving at least 12 people dead and 25 others wounded from both sides, officials said on Sunday, just two days ahead of the implementation of a cease-fire agreed in talks in Sweden earlier this week.

Fighting between Saudi-led coalition forces and Yemen's Shiite rebels has flared up again around the Red Sea port city of Hodeida, despite U.N. calls for a cease-fire, Yemeni officials and witnesses said Tuesday.

An informal agreement to reduce hostilities between Saudi-led coalition forces and rebels in and around Yemen's Red Sea port city of Hodeida has taken hold, military officials said Tuesday, in a move that could be a prelude to peace talks that would end the ruinous war in the poorest Arab country.

Forces loyal to the Saudi-led coalition fighting Houthi rebels advanced on Monday to within 5 kilometers (3 miles) of the port facilities in Yemen's contested Red Sea city of Hodeida, the current epicenter of the civil war, officials said.

Fighting has escalated around Yemen's key port city of Hodeida, with more than 150 combatants killed over the weekend from both the rebel and government-backed sides, officials said Sunday.
