Lisbon – An East Timorese couple has been killed by Indonesia's intelligence service, Intel, the Timorese Socialist Association (AST) has said.

Quoting clandestine sources, the resistance movement said in a statement on Friday that the two had been killed last Wednesday night inside their house.

AST said also four East Timorese youth had been arrested, and that it did not know their whereabouts.

Last Thursday morning, an ambush by East Timorese rebel forces in the area of Kailui, killed one Indonesian capitan, three sergeants and two soldiers.

Indonesia invaded East Timor in 1975 and annexed it one year later in a move not recognised by the United Nations that still regard Portugal as the territory's administering power.
