(Compass) – A 24-year-old Christian man in Zamboanga City , Philippines , is recovering from serious injuries after being shot by Muslim activists on November 17. Friends and family have asked that the victim not be identified by name, as they believe the three men who attacked him and left him for dead are likely to come back to finish the job. In recent years, efforts to spread Islam among the majority Christian population have increased. Several Muslim terrorist organizations exist in the Philippines , such as the Abu Sayyaf and the Moro Islamic Liberation Front, which have been linked to Al-Qaeda. According to police sources, the groups are attracting new converts to Islam in greater numbers than Muslims born into the faith. Converts are ideal terrorists because they are eager to prove themselves worthy of their new faith, Chief Superintendent of Police Rodolfo Mendoza recently told a journalist.
