From The Australian:

An elite Australian Special Air Service team of about 20 soldiers has been involved in a joint military operation in the southern Philippines to hunt down Asia's most wanted terrorists, including two of the 2002 Bali bombers. The SAS has been participating in a US-Philippines military campaign to eradicate the Abu Sayyaf terror outfit, which is believed to have been sheltering senior Indonesian Jemaah Islamiah terrorists Dulmatin and Umar Patek. The campaign, centred on the Abu Sayyaf stronghold of Jolo island in Mindanao, has been running for more than two months. Sources told The Weekend Australian it involved about 100 US special forces, including Green Berets, Navy SEALs and CIA counter-terrorism specialists, as well as the armed forces of The Philippines.
