Four Yemeni soldiers were killed in a Sunday suicide attack on a checkpoint near the international airport in second city Aden, a security official said.
“A suicide bomber driving a bomb-laden vehicle blew himself up on Sunday upon arrival at a checkpoint near Aden airport,” the official told AFP.
“Four soldiers were killed and two others were wounded,” he added, without blaming any group for the attack.
On Friday, a car bomb exploded in the port city near a building housing the foreign ministry, without causing casualties, security sources said.
ISIL terrorist group claimed responsibility for that attack and also for a suicide bombing Tuesday in Aden targeting army recruits that killed five.
Yemen has been since March 26, 2015 under brutal aggression by Saudi-led coalition.
Thousands have been martyred and injured in the attack, with the vast majority of them are civilians.
Riyadh launched the attack on Yemen in a bid to restore power to fugitive president Abd Rabbu Mansour Hadi who is a close ally to Saudi Arabia.
