Thursday's bombing targeted the Saada near the Saudi border, a Huthi official told DPA.

"Other people were wounded in the fierce bombardment that also damaged some buildings," the official said.

The strikes were the latest by the Saudi against Saada in an air campaign now in its third month.

Saudi Arabia have been targeting the Houthis and Ansarallah revolutionary Forces and allied military units since March 26, to restore former president Abd Rabu Mansour Hadi.

The United Nations is trying to bring the exiled president and the oppositions to negotiations to end the conflict in Yemen, which is the Arab world's poorest country.

A senior official from Yemen's dominant Houthi group said the movement will attend U.N.-backed peace talks in Geneva planned for June 14 without preconditions.

"The group will participate in the Geneva talks and it supports without preconditions the efforts of the United Nations to organise Yemeni-Yemeni dialogue," Daifallah al-Shami, a senior Houthi official, told Reuters.

Saudi-led air strikes also killed a group of around 20 people outside the southern Yemeni port city of Aden on Wednesday and also shook the capital Sanaa in the north, witnesses said.
