Fighting broke out on the outskirts of Yemen's port city of Hodeida Friday, residents said, a day after a ceasefire agreement was reached by the warring parties at U.N.-sponsored peace talks.

One resident told Reuters he could hear the sound of missiles and automatic gunfire in the direction of the eastern 7th July suburb of the Houthi-held city, on whose outskirts Yemeni forces backed by the Arab coalition have massed.

The Iran-backed Houthi rebels and the Saudi-backed government had agreed after a week of consultations in Sweden to cease fighting in the Red Sea city and withdraw their troops.

It was the first significant breakthrough for U.N.-led peace efforts to pave the way for political negotiations to end the nearly four-year-old war that has killed tens of thousands of people and pushed Yemen to the brink of famine.

Envoy Martin Griffiths said at the end of the talks that both parties would withdraw "within days" from the port, a lifeline for millions facing starvation, and then from the city. International monitors would be deployed and all armed forces would pull back completely within 21 days.
