The United States Navy has reportedly joined Saudi Arabia’s airstrikes against Yemen, according to a military source.

US warships took part in an air assault against Yemenis on Monday, the source has told a Russian media outlet.

"American ships participated in yesterday's airstrikes on Sanaa, specifically, they launched a cruise missile on a strengthened missile brigade,” the source told Sputnik on Tuesday.

The airstrike began after Saudi warplanes failed to hit weapons depots belonging to Ansarullah revolutionaries of the Houthi movement, the source noted.

On Monday, the Saudi-led airstrikes targeted the Houthi’s missile site in the southern Sana’a neighborhood of Faj Attan, according to witnesses.

The announcement of US participation is the first one showing a collaboration between the US military and Saudi Arabia in the attack on Yemen.

President Barack Obama has expressed his support for the assault on the people of Yemen one day after the airstrikes began on March 26.

In the latest air raid on Wednesday, 29 people were killed and 24 more injured. The airstrike targeted a food factory in the western Yemeni province of Hudaydah.

Saudi Arabia started air campaign in Yemen in a bid to restore power to fugitive former Yemeni President Abd Rabbuh Mansur Hadi, a close ally of Riyadh.

Hadi stepped down in January and refused to reconsider the decision despite calls by Ansarullah revolutionaries.

He fled Aden to the Saudi capital Riyadh after Ansarullah fighters advanced toward the southwestern Yemeni city, where he had sought to set up a rival power base, and where he withdrew his resignation.
