An airstrike by a Saudi-led coalition targeting Shi'ite rebels in Yemen's southern province of Taiz killed 25 people - 15 fighters and 10 civilians.
Tuesday's airstrike also wounded eight civilians, officials said. Most of the victims were shoppers or storekeepers in the area that was hit, a commercial road that lies between two villages.
The Taiz attack came amid an uptick in coalition airstrikes on Monday night and early Tuesday, the officials said, adding that the fighting also raged east of the capital, Sanaa.
Yemen's conflict pits rebels known as Houthis and their allies against the internationally recognised government, backed by the Saudi-led coalition of mainly Arab states. The conflict has killed an estimated 9,000 people and pushed the Arab world's poorest country to the brink of famine.
Meanwhile, senior military commander Major General Farag al-Bohsony said the death toll from a series of attacks on Monday night in the southern city of Mukalla rose to 48.

He said the attacks, blamed on Yemen's Islamic State affiliate, also wounded 30 people.
The attacks targeted intelligence offices, army barracks and checkpoints. In one, a bomb was concealed in a box of food brought to soldiers at a checkpoint to break their dawn-to-dusk Ramadan fast. In another, a group of militants stormed a police station. Al-Bohsony said the victims included two colonels and three civilians, one of them a child.
The violence came as the government and the Houthis were said to be planning to suspend talks on ending the conflict after failing to reach a breakthrough in two months of negotiations in Kuwait.
