INDONESIA, MALAYSIA, PHILIPPINES TO JOIN FORCES VS MILITANTS

Indonesia says it's looking to set up joint patrols with the Philippines and Malaysia to prevent Islamic militants who have laid siege to Marawi City in southern Philippines from entering its territorial waters.

Indonesia's military chief, Gen. Gatot Nurmantyo, said late Monday that he and Defense Minister Ryamizard Ryacudu would meet next week with their counterparts from Malaysia and the Philippines on Indonesia's Tarakan island in northern Borneo, just across the border from Sabah, Malaysia.

He said they'll discuss increasing security and signing an agreement to step up joint patrols.

Nurmantyo, speaking with reporters and military officials in the capital, Jakarta, said Indonesia needs to be aware of the movement of Muslim militants in the Philippines who assaulted Marawi three weeks ago because Indonesia already has sleeping cells that most likely have been long embedded in the country.

He said Islamic State-affiliated cells exist in all of Indonesia's provinces except Papua.

Authorities in Indonesia, the world's most populous Muslim-majority nation, have carried out a sustained crackdown on militants since the 2002 bombings by al-Qaida-affiliated radicals that killed 202 people in Bali.

In recent years, it has faced a new threat as the rise of the Islamic State group in the Middle East has breathed new life into local militant networks and raised concerns about the risk of Indonesian fighters returning home.

Marawi is located about 500 kilometers north of Sangihe island in Indonesia's North Sulawesi.

Maj. Gen. Ganip Warsito, the regional military chief overseeing the closest areas to neighboring Philippines said Indonesia army, navy and air force have deployed extra troops to boost security in the region.

"So far, we have not found any indication of Islamic militants infiltrating from the Philippines to our territory," Warsito said. "We have conducted intelligence, territorial and combat operations to anticipate it."

The Islamic State group has called on supporters to carry out attacks in the United States and Europe during the Muslim holy month of Ramadan that began two weeks ago.

In an audiotape circulated online Monday, spokesman Abu al-Hassan al-Muhajer praised last week's attacks in Iran's capital, saying the country is "weaker than a spider's web" and calling for more assaults.

Al-Muhajer also called for attacks in Russia and Australia, saying "heaven is reached under the shadow of swords."
