The landslide happened on Tuesday night outside a gold mining site in the town of Maco in the province of Davao de Oro where the buses were picking up employees, mining operator Apex Mining said in a statement.

It was not immediately clear how many passengers were on board the buses.

Those injured, including one in critical condition, were taken to a hospital, Maco town's disaster agency said in a Facebook post on Wednesday.

The disaster agency also issued evacuation orders in five villages in Maco, located on the island of Mindanao.

A northeast monsoon and a trough of low pressure has brought rains in southern Mindanao region from Jan. 28 to Feb. 2, resulting in deadly floods and landslides, data from the national disaster agency show.
