Police found (outside the capital of Basilan island) the heads of two Filipino hostages killed by Abu Sayyaf. The body of a dead American hostage has not yet been found. Abu Sayyaf has threatened to kill more of their hostages if the government does not withdraw its troops and agree to negotiate (that is, pay ransom.) The army reported that troops were slowly advancing towards the main Abu Sayyaf camp. Elsewhere, troops killed seven NPA rebels in two incidents.
