A Saudi Black Hawk helicopter has crashed during the regime’s operations in Yemen.

The crash occurred on Tuesday, and killed 12 officers, Saudi news agency SPA reported.

The SPA quoted a military statement as saying that the helicopter came down in Marib province, east of the capital Sanaa.

“As a result, four officers and eight non-commissioned officers from the Saudi armed forces were martyred,” it said.

The Saudi news agency gave no details on the cause of the crash, noting it was under investigation.

Sine a coalition of Arab countries began their aggression against the Houthi movement in 2015, thousands of civilians have been killed and injured in Yemen.

Saudi Arabia’s intention is to reinstall former Yemeni President Abd-Rabbu Mansour Hadi to power.

The Houthi popular movement, seized much of northern Yemen, including the capital Sanaa, during a series of military operations beginning in 2014, that eventually forced Hadi to flee.

The Houthis consider their movement in the Arab country as a revolution against corruption.

Saudi Arabia’s military campaign against Yemen has seriously damaged the country’s infrastructure. Local Yemeni sources have put the death toll from the Saudi war at over 12,000, which includes many women and children.
