Saudi-led strikes targeted more than 20 Houthi militia positions across Yemen late on Sunday, according to residents.
Three raids on the Houthi-controlled international airport in Aden were reported, as well as strikes in Hajja province along Yemen's border with Saudi Arabia, according to Reuters news agency. Houthi militias have repeatedly clashed with Saudi forces on the border in recent weeks.
A Saudi-led military coalition has been bombing the Houthis for three months to restore the country's exiled government.
The Houthis took over the capital Sanaa in September and spread throughout the country in a push they view as a revolution against Yemeni President Abdrabbu Mansour Hadi. They are fighting Hadi, who is exiled in Riyadh, and southern separatists, tribal factions and other political groups.
The Houthis are allied to Yemen's deposed president Ali Abdullah Saleh, who still has the loyalty of much of the army.
Yemen’s foreign minister on Friday said talks that brought the country’s warring sides together in Geneva ended without reaching any agreement, blaming the Iran-backed Houthi militia delegation for hindering the talks, Al Arabiya News Channel reported.
Riyad Yassin also said there was no agreement on whether to hold a second round of negotiations in the Swiss city.
“There was no agreement,” said the U.N. special envoy for Yemen, Mauritanian diplomat Ismail Ould Cheikh Ahmed, who added that if a new round of talks were held, an agreement on a ceasefire could be achieved “pretty soon.”
No date had been set for new talks, he said. More than 2,600 people have been killed since the Saudi-led alliance began its air campaign in March, according to the United Nations.
