Saudi-led air strikes killed at least 19 people across Yemen on Tuesday, Yemeni sources said, a day after Saudi Arabia said shells fired from Yemen had killed two of its soldiers.
The fighting comes amid continued preparations to bring representatives of the Yemeni government, the Iranian-backed Houthi group and former President Ali Abdullah Saleh to talks in Geneva next week.
Yemeni sources said nine Houthi fighters were killed in air strikes on their positions in oil-producing Marib province, east of the capital Sanaa, while four others died in the central Ibb province.
Houthi officials were not immediately available to comment on those reports.
But the state news agency, controlled by the Houthis, said three women had been killed by shelling in Haidan, in the northern Saada province. The agency also said three Yemenis had been killed and four injured in the Hamdan district of Sanaa.
The reports could not be independently verified.
