The Saudi-led coalition bombing Yemen denied Sunday renewed accusations of dropping cluster munitions in the country after UN chief Ban Ki-moon said their use may be a "war crime".

Coalition spokesman Brigadier General Ahmed al-Assiri told AFP that the alliance "denies using cluster bombs in Sanaa", the Yemeni capital.  

He was responding to a report issued Thursday by the US-based Human Rights Watch (HRW), which quoted Sanaa residents describing a January 6 attack consistent with airdropped cluster bomb use.

Yemen has been since March 26 under brutal aggression by Saudi-led coalition.

Hundreds of 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.

However, Yemeni army, backed by the committees has been responding to the aggression by targeting several Saudi border military posts and cleansing several areas across the country, especially the country’s south, from Hadi and al-Qaeda-linked militias.
