At least 22 people have been killed and more than 50 wounded in an attack at the airport in the southern Yemeni city of Aden, officials say.
There was at least one explosion shortly after a plane carrying the war-torn country’s newly formed government arrived from neighbouring Saudi Arabia.
Aid workers and officials were among the casualties. But the prime minister said he and his cabinet were “fine”.
The information minister accused Houthi rebels of a “cowardly terrorist act”.
Yemen has been devastated by a conflict that escalated in 2015, when a Saudi-led coalition of Arab states launched a military operation to defeat the Houthis and restore President Abdrabbuh Mansour Hadi’s rule.
The fighting has reportedly left more than 110,000 people dead; triggered the world’s worst humanitarian disaster, with millions on the brink of famine; and left the country even more vulnerable to the Covid-19 pandemic.
Video footage of Wednesday’s incident showed that there was a large blast as passengers began leaving the plane that had flown the new cabinet to Aden.
A crowd that had gathered on the tarmac to welcome the ministers fled as thick smoke billowed from the airport terminal. The sound of gunfire was heard soon afterwards.
An AFP news agency correspondent reported hearing at least two blasts in total, as did Minister for International Co-operation Najeeb al-Awj.
The cause was not clear, but a security source told Reuters news agency that three mortar shells landed on the terminal.
Saudi television channel Al-Hadath meanwhile broadcast a video that it said showed a missile hitting the tarmac and exploding.
In August 2019, 36 people were killed in a Houthi missile attack on a military parade in Aden.
The International Committee of the Red Cross (ICRC) said a member of staff was killed in Wednesday’s attack, and that two others were unaccounted for and three were injured.
“Our staff were transiting through the airport with other civilians. This is a tragic day for us and the people of #Yemen,” it tweeted.
Yemeni news website Al-Masdar Online reported that an undersecretary at the labour ministry, Yasmin al-Awadhi, was killed and that Deputy Minister of Youth and Sport Moneer al-Wajeeh and Deputy Transport Minister Nasser Sharif were among the injured.
Prime Minister Maeen Abdulmalik Saeed and his cabinet were taken to safety following the attack.
Mr Saeed tweeted: “We and the members of the government are in the temporary capital of Aden and everyone is fine.
“The cowardly terrorist act that targeted Aden airport is part of the war that is being waged against the Yemeni state and its great people,” he added, without directly blaming the Houthis.
“It only increases our determination to carry out our duties.”
UN special envoy Martin Griffiths strongly condemned the attack.
“I wish the cabinet strength in facing the difficult tasks ahead,” he said in a statement. “This unacceptable act of violence is a tragic reminder of the importance of bringing Yemen urgently back on the path towards peace.”
Later on Wednesday there was another explosion near the Maashiq presidential palace where the prime minister took refuge. Saudi-funded Al Arabiya TV reported that an explosive drone was shot down. (Courtesy BBC)
