ISTANBUL (AP) — A Turkish man was charged Friday with murder in the stabbing death of a Roman Catholic bishop, the Vatican's apostolic vicar in Anatolia, for whom he worked as a driver, a court said.

The killing of Monsignor Luigi Padovese outside his home in the Mediterranean port of Iskenderun on Thursday was the latest in a string of attacks in recent years on Christians in predominantly Muslim Turkey, where Christians make up less than 1 percent of the 70 million population.

The 26-year-old driver, Murat Altun, confessed to the killing, his lawyer Cihan Onal said.

"The murder is not politically motivated," Onal told the state-run Anatolia news agency. "My client is suffering from mental problems. He confessed to all the details of the killing."

Turkish authorities also said the murder did not appear to be politically motivated. The court in Iskenderun ordered Altun jailed pending trial. No trial date has been set.

Onal said the driver would undergo medical tests to determine his mental health.

"In his statement, at one point he said he killed him after receiving a message from God," Onal said. "He can't explain why he committed the murder. In fact, he is giving conflicting accounts."

Onal rejected allegations that Altun, a Muslim, had converted to Christianity.

Padovese had been due to fly to Cyprus on Friday with his chauffeur to meet Pope Benedict, who is going to the island to invite Roman Catholic clerics in the Middle East to a synod in Rome.

Turkish authorities and a Franciscan nun, Sister Eleonora de Stefano, who reportedly had spoken to Padovese on the phone less than an hour before his slaying, said the bishop's driver was lately suffering from serious depression.

Sister de Stefano said Padovese had asked her "to cancel Murat's ticket for Cyprus as well for himself because he hadn't been feeling well," the Italian agency ANSA has reported.

"Since Murat was suffering from a serious depression for at least two weeks. Recently, he frequently met with Monsignor Padovese, who was trying to help him," ANSA quoted the nun as saying. "He had even asked him to accompany him to Cyprus, but the driver refused."

Turkish authorities said the body of Padovese could be flown home after an autopsy in the southern city of Adana.

The Turkish government has paid tribute to Padovese, who was appointed apostolic vicar in Anatolia in 2004, with Culture Minister Ertugrul Gunay saying he had "made important contributions to the culture of tolerance through his services in Hatay."

There has been several attacks on Christians in Turkey in recent years.

In 2007, a Roman Catholic priest in the western city of Izmir, Adriano Franchini, was stabbed and slightly wounded in the stomach by a 19-year-old man after Sunday Mass. The man was arrested.

The same year, a group of men entered a Bible-publishing house in the central Anatolian city of Malatya and killed three Christians, including a German national. The five alleged killers are now standing trial for murder.

In 2006, amid widespread anger in Islamic countries over the publication in European newspapers of caricatures of Islam's Prophet Muhammad, a 16-year-old boy shot dead a Catholic priest, Father Andrea Santoro, as he prayed in his church in the Black Sea city of Trabzon. The boy was convicted of murder and sentenced to 18 years in prison.
