Coalition spokesman Brigadier General Ahmed Assiri denied a major ground force had landed in Aden, telling the Saudi Al-Ekhbariya news channel: “I can assure you that no (coalition) forces disembarked on the ground in Aden today.”
But, speaking to the Doha-based Al-Jazeera news channel, he said the coalition “cannot comment on future or ongoing operations” and that “all options are open”.
“The coalition leadership will not spare any effort to support the resistance and achieve positive results on the ground,” Assiri said.
The coalition declared an end to its Operation Decisive Storm air strikes on April 21, saying the campaign would enter a new phase dubbed Renewal of Hope focused on political efforts, aid deliveries and “fighting terrorism”.
But air strikes have continued and the coalition has faced increasing criticism for its campaign.
At least 1,200 people have been killed in Yemen since late March and thousands more have been wounded.
Human Rights Watch on Sunday accused the coalition of using US-supplied cluster bombs in its operation, warning of the long-term danger to civilians.
The widely banned bombs contain dozens of submunitions, which sometimes do not explode, becoming de facto landmines that can kill or maim long after being dropped. HRW said it had gathered photographs, video and other evidence indicating that cluster munitions had been used in air strikes against the Huthi rebel stronghold of Saada province in Yemen’s northern mountains in recent weeks.
Cluster munitions are prohibited by a 2008 treaty adopted by 116 countries, but not by Saudi Arabia and its coalition partners or the United States.
“Saudi-led cluster munitions air strikes have been hitting areas near villages, putting local people in danger,” said HRW arms director Steve Goose.
“Saudi Arabia and other coalition members — and the supplier, the US — are flouting the global standard that rejects cluster munitions because of their long-term threat to civilians.”
Saudi Arabia denied it was using cluster munitions earlier in the campaign.
HRW said munitions used in Yemen appeared to be the CBU-105 Sensor Fuzed Weapons manufactured by the Textron Systems Corporation and supplied to both Saudi Arabia and the United Arab Emirates by the United States in recent years.
