A South Korean married couple living in the Philippines have been missing for months, the foreign ministry here said Monday, adding that it is working in cooperation with local authorities to discover their whereabouts.

The couple was last seen in April when they took a ship leaving from Samar Island located near the Philippines' southern island of Mindanao, according to the ministry.

They are said to have lived in Mindanao for about one year. The Seoul government currently has a travel ban for its nationals to some parts of the island due to safety concerns.

Detailed information on the couple, including their identity and age, has not been released.

The ministry said that it has been working with local police and relevant authorities to find the couple.

The number of South Korean nationals killed in the Philippines stands at six so far this year. Last year, a total of 11 Korean nationals were killed in the country, according to the ministry. (Yonhap)
