THE HAGUE, Netherlands (AP) : The prosecutor of the International Criminal Court said Friday he will seek arrest warrants next week related to a deadly attack on African Union peacekeepers in Sudan's Darfur region.

The case is the first by the world's first permanent war crimes tribunal to target Darfur rebels, who are fighting government troops and the allied janjaweed militia of Arab nomads in a five-year conflict that has left up to 300,000 dead.

Luis Moreno-Ocampo said his third Sudan investigation is focused on attacks in the northern Darfur town of Haskanita.

He gave no further details during a speech Friday, but earlier said he was investigating a rebel attack on the Haskanita military base on Sept. 29, 2007, that left 10 African Union soldiers dead and one missing.

Richard Dicker of Human Rights Watch welcomed the announcement.

``We have not seen his application, but the significance must be the seriousness of killing ... those who are mandated to protect civilians at risk,'' Dicker told The Associated Press.
