Saudi Arabia has denied reports of deploying a limited number of ground troops in Yemen's second city of Aden.

Saudi-led coalition spokesman Brigadier Ahmad Assiri said the Arab coalition remained engaged in the fight in the Arabian Peninsula nation through conducting airstrikes and arming the local resistance.

"There are no foreign forces in Aden, but the coalition continues to help fight against the Houthi militia," Brigadier General Ahmed al-Assiri said in a statement.

Assiri added that if the Arab coalition decided on such a move, it would be announced to the press.
