Warplanes from a Saudi-led coalition have hit a stronghold of Yemen's Iran-backed Shi'ite Huthi rebels, killing at least 30 people.
Thursday's bombing targeted the Huthis' northern holdout of 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.
He did not say if the casualties included civilians.
The strikes were the latest by the Saudi-led alliance against Saada in an air campaign now in its third month.

Saudi Arabia and other Sunni Arab countries have been targeting the Huthis and allied military units since March 26, when those groups forced internationally recognised President Abd Rabu Mansour Hadi to flee the country.
Hadi, a Sunni, is now staying in Saudi Arabia.
The United Nations is trying to bring the exiled president and the rebels to negotiations to end the conflict in Yemen, which is the Arab world's poorest country.
