Sana'a: As the Saudi-led coalition in Yemen prepared to reopen airports and seaports there, a deadly suicide bombing hit near a camp used by a local security force.

Witnesses said that two suicide bombers detonated a car packed with explosives in Yemen's southern city of Aden, killing at least six people. Read more details

Dozens of other people, including civilians, were wounded in the attack, which occurred outside a camp used by a local security force organised by the Saudi-led coalition fighting Yemen's Houthi rebels.

Saudis look to relax blockade

The Saudi-led coalition on Monday said it will begin relaxing a blockade in Yemen soon. 

"The first step in this process will be taken within 24 hours and involves reopening all the ports in areas controlled by" Yemen's internationally recognised government, which the coalition backs, read the mission's statement.

Those ports are in Yemeni cities of Aden, Mocha and Mukalla. For ports in rebel-held or disputed territories, such as the city of Hodeida, the mission said it has asked the UN to send a team of experts to discuss ways to make sure weapons can't be smuggled in.

The Saudi-led coalition hopes that will prevent "the smuggling of weapons, ammunitions, missile parts and cash that are regularly being supplied by Iran and Iranian accomplices to the Houthi rebels," the statement said.

Despite the Saudi announcement, a top leader of Yemen's Shiite rebels on Monday vowed retaliation against the oil-rich kingdom over its disastrous blockade of his war-torn country. The war has killed over 10,000 civilians, displaced 3 million people and left much of the infrastructure in ruins.
