The Philippine military said it killed three of Southeast Asia’s most-wanted terrorist leaders in a U.S.-backed airstrike that significantly weakens an al-Qaida-linked network that had used islands in the southern Philippines as a hideout and training base....Malaysian Zulkifli bin Hir, also known as Marwan, a top leader of the regional Jemaah Islamiyah terror network...the leader of the Philippine-based Abu Sayyaf militants, Umbra Jumdail, and a Singaporean leader in Jemaah Islamiyah, Abdullah Ali, who used the guerrilla name Muawiyah...
I note the air strike was 0300hrs by two OV10s dropping 4 x500lb bombs and no-one is being specific what the US help was.
