The roar of bombardment mingled with the wail of sirens in Sana on Tuesday as the first Saudi-led airstrikes since the end of a five-day cease-fire hit the Yemeni capital.
In Riyadh, the capital of neighboring Saudi Arabia, three days of talks ended with a communique denouncing the "coup" against Yemen's president by Shiite Muslim Houthi rebels and their allies, who are loyal to the exiled leader's predecessor. The Houthis had boycotted the conference.
Tuesday’s airstrikes in Sana, which began before dawn and continued into the afternoon, targeted positions and arms caches of Houthi militias and forces aligned with deposed strongman
The airstrikes in Sana, some of which triggered powerful secondary explosions, set off panicky civilian flight in the district of Niqum, with hundreds of families abandoning their homes and adding to the estimated half-million people internally displaced by the conflict. Some people made makeshift encampments in the garbage-strewn streets.
Over the last seven weeks, aerial bombardment by a Saudi-led coalition has frequently hit in or near residential areas. There was no immediate word on casualties resulting from Tuesday's strikes.
Coalition warplanes also pummeled Aden, where forces loyal to exiled President Abdu Rabu Mansour Hadi have been battling Houthis and Saleh-linked forces in the streets. The southern city of Dali was hit for a second day.
The stated aim of the Saudi-led offensive is to restore the rule of Hadi, who fled Yemen earlier this year and found haven in Riyadh. Tuesday's communique issued in Riyadh urged a "national reconciliation initiative" in Yemen, and demanded that the insurgents be brought to justice.
Saudi Arabia and its Sunni Muslim allies launched their air offensive on March 26, as Houthis were advancing on Aden, the country's main commercial hub. Months earlier, the rebels had seized Sana and made substantial territorial gains elsewhere in the impoverished country at the tip of the Arabian Peninsula.
The Saudi-led coalition so far has not sent ground troops into Yemen, but Houthi forces have been aiming mortar and artillery fire across the long border with Saudi Arabia, and have at times clashed with Saudi forces on the frontier.
