Air strikes hit Yemen after truce expires

Saudi-led coalition airstrikes resumed early Monday in the southern port city of Aden after a five-day truce ended following talks on the country's future that were boycotted by the rebels. 

The cease-fire hadn't halted all fighting in Yemen between the rebels, known as Houthis, and government forces loyal to exiled President Abed Rabbo Mansour Hadi. 

Earlier Sunday, hundreds of Yemeni politicians and tribal leaders gathered in Saudi Arabia for three days of talks on Yemen's future, but the Houthis refused to participate. 

The rebels reject the main aim of the talks,  the restoration of Hadi, who fled the country in March in the face of rebel advances, and the location of the negotiations in Saudi Arabia, which is leading an air campaign against the Houthis and their allies. 

The absence of the Houthis means the national dialogue is unlikely to end the violence. 

The UN envoy to Yemen, Ismail Ould Cheikh Ahmed, opened the meeting in Riyadh by calling on all parties to ensure that the shaky cease-fire leads to a lasting truce.

"I call on all parties to refrain from any action that disturbs the peace of airports, main areas and the infrastructure of transport," said Ahmed, speaking on behalf of UN Secretary-General Ban Ki-moon. 

Since late March, Saudi Arabia has led airstrikes against the Houthis and allied military units loyal to former President Ali Abdullah Saleh. The campaign is aimed at weakening the Houthis and restoring Hadi, who addressed the talks Sunday. 

"This conference taking place today is in support of politics and community, and rejects the coup," Hadi told the gathering. 

He urged a return to the political road map through which Saleh stepped down after more than three decades in power following a 2011 Arab Spring-inspired uprising.

Saleh's ouster and the road map was backed and overseen by the six-nation Gulf Cooperation Council, which is headquartered in Saudi Arabia, as well as the UN  and the US.  

Among those taking part in the conference are members of Saleh's former ruling party. 

Yemen's conflict has killed more than 1,400 people, many of them civilians since March 19, according to the UN.

The country of some 25 million people is enduring severe shortages of food, water, medicine and electricity as a result of a Saudi-led blockade.

Humanitarian organizations had been scrambling to distribute aid before the end of the truce. 

That includes an Iranian cargo ship carrying humanitarian aid en route to Yemen. Iranian state television quoted Nasser Charkhsaz, the head of the Iranian Red Crescent's Relief and Rescue Organization, as saying that the ship is currently sailing in international waters near Oman's Salalah port and will arrive at the Bab el-Mandeb strait between Yemen and Djibouti and Eritrea in two days. 

According to the report, the ship is scheduled to reach Yemen's port city of Hodeida by Thursday if plans go smoothly. 

Western countries accuse Iran of backing the Houthi rebels, something the Islamic Republic and the rebels deny.

Meanwhile, a suspected US drone strike hit a car carrying a group of people, Yemeni security officials said. The strike was in Shabwa province.

The officials spoke on condition of anonymity because they were not authorized to speak to reporters.
