Intense fighting broke out in Yemen's port city of Hodeida late on Monday, shattering a lull in violence that had raised hopes for a ceasefire between a Saudi-led coalition and Houthi insurgents as the United Nations tried to resume peace talks.

Coalition warplanes conducted more than 10 airstrikes on Houthi positions and battles could be heard in the "July 7" district, 4 km (2.5 miles) away from the port, residents said. One resident said a medium-range missile had been fired from the city center toward the district in the suburbs.

The coalition led by Saudi Arabia and the United Arab Emirates had last week ordered a halt in its offensive against the Houthi-held Red Sea port city, now a focus of the war, amid pressure from the West to end a conflict that has pushed Yemen to the brink of famine.
