Saudi Arabia’s mission to the United Nations has announced that Riyadh and its allies will reopen airports and seaports in Yemen.

The announcement comes after the United Nations and over 20 humanitarian groups strongly condemned Saudi Arabia’s siege against Yemen.

They also warned that the blockade could bring millions of people closer to “starvation and death.”

On Monday, the mission said that “the first step in this process will be taken within 24 hours and involves reopening all the ports” in areas controlled by the Saudi-backed former Yemeni government.

Those ports are located in Aden, Mocha and Mukalla in southern Yemen.

Earlier this month, Houthi fighters targeted an international airport near the Saudi capital, Riyadh.

Following the incident, Saudi Arabia announced that it was shutting down air, sea and land borders with Yemen, which is already dealing with a terrible humanitarian situation in the face of a crippling siege.

In retaliation for Saudi Arabia’s continued attacks against Yemen and the siege imposed on the Yemeni ports, the Houthis on Sunday threatened to target battleships and oil tankers of Saudi Arabia and its allies.

Since 2015, Saudi Arabia and its allies launched a military campaign against Yemen to reinstall former Yemeni President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.

Ever since, over 12,000 Yemeni people have been killed as a result of the Saudi-led military coalition.
