Five Sudanese soldiers of the Saudi-led coalition were killed Wednesday when a blast struck their military vehicle in Yemen's northwestern province of Hajjah, a government official said.

The explosion killed at least five Sudanese soldiers at the scene and seriously wounded three others, the official said on condition of anonymity.

Sudanese military units have been participating in the Saudi-led coalition forces fighting against the Houthi militia in Yemen since March 2015.

Large areas of the war-torn country witness almost daily mine explosions, resulting in human and material losses. Previous reports by humanitarian organizations said Yemen has become one of the largest landmine fields in the world since World War II.

The Houthis seized the northern Yemeni provinces including the capital Sanaa in late 2014, forcing President Abdu-Rabbu Mansour Hadi and his government into exile.

A coalition formed by Saudi Arabia and several other Arab countries intervened militarily in the conflict to fight against the Houthis in March 2015, in response to an official request from Hadi to protect Yemen.
