The four remaining Indonesians held captive by the Abu Sayyaf militant group in The Philippines have been released, President Joko "Jokowi" Widodo said on Wednesday.

The Indonesian sailors, kidnapped by the militant group in April, are now in the hands of the Philippine authorities and will be handed over to the Indonesian government soon, Jokowi said at the State Palace as reported by kompas.com.

He gave no further details regarding the release.

The four sailors had been employed as crew aboard the Henry, a tugboat, and Christie, a barge, sailing in Malaysian and Philippines' waters in mid-April when they were taken hostage by the Abu Sayyaf militant group. (afr/rin)
