The Saudi-led coalition has resumed airstrikes against Shi'ite rebels in Yemen after the end of a five-day humanitarian cease-fire.
The cease-fire expired late Sunday and the coalition airstrikes hit rebel positions in the southern port city of Aden.
Since late March, the coalition has been bombing Iran-backed Houthi rebels in Yemen who had seized Sana'a.
Earlier Sunday, Yemeni political leaders met in the Saudi capital, Riyadh, to discuss a negotiated settlement to the ongoing conflict. No representative of the Houthi rebel group attended.
The Houthis have rejected the main aim of the three-day talks -- the restoration of Yemen's internationally recognized President Abdrabbu Mansour Hadi.
Mr. Hadi told the conference attendees that the Yemeni people await stability, which can only come if the country's legitimate government and its institutions are restored and the Houthi rebels are disarmed. He denounced the group's power grab last year after a national political power-sharing agreement had been reached.
The United Nations says more than 1,500 people have been killed, 6,200 wounded and 450,000 have become displaced in the Yemen conflict.
