Warplanes targeted Yemen's Huthi rebels and their allies in the capital, Sanaa, and other areas on March 27, the second day of a Saudi-led aerial campaign aimed to stop the Shi'ite militia from establishing its rule across Yemen.
Western news agencies quoted local residents as saying strikes targeted the presidential palace in Sanaa.
Other areas hit included military installations in the oil-producing Marib region and the Anad air base north of the southern port city of Aden, local officials said.
The Huthis' northern stronghold of Saada, near the Saudi border, was also bombarded overnight, independent Yemeni news site Barakish.net reported.
Yemeni health officials said at least 39 people were killed in two days of air strikes.
Sunni-led Saudi Arabia and its allies believe the rebels are tools for Iran to seize control of Yemen and say they intend to stop the takeover. Reports say the Saudis have mobilized 150,000 troops near the border.
The Huthis control much of Yemen's north and several southern provinces.
Meantime, Yemen's president, Abd-Rabbu Mansour Hadi, has arrived in the Egyptian resort of Sharm el-Sheikh for a weekend Arab League summit at which the events in Yemen are expected to top the agenda.
Yemeni Foreign Minister Riyadh Yaseen told journalists ahead of the summit there was a possibility of dialogue with Huthi rebels.
"We have also stressed that dialogue is a necessity," he said. "But the dialogue that is required is one that is under the auspices of the legitimacy of the president and the state, and not the coups or the militias that are seizing all state's abilities and are legalizing everything for Iran's takeover."
