MANILA, Sept. 15 (Xinhuanet) -- Sixty-three members of the Moro Islamic Liberation Front (MILF), the biggest rebel group in the Philippines, have surrendered to the authority in the southern province of Northern Cotabato, a military report said.

　　Four field commanders were among those who gave themselves in to the Philippine Army 38th Infantry Brigade in Midsayap town, the military said in a report reaching Manila on Monday morning. The MILF, however, denied the report immediately afterwards.

　　The 12,000-strong MILF has been waging a 25-year-old insurgence war in Mindanao in the south. A new round of formal peace talks between the MILF and the government, which had been set in August in Kuala Lumpur of Malaysia, was put off to October. Enditem
