A massive crowd of Filipino Roman Catholic devotees jammed Manila's streets Saturday for an annual procession of a centuries-old statue of Jesus Christ, which was held under extra heavy security following the Paris attacks.

About 5,000 police and soldiers were deployed to secure the daylong procession of the Black Nazarene in one of Asia's largest religious festivals, although no specific threat has been monitored. The huge crowd has reached more than a million by Saturday noon, Manila police Chief Superintendent Rolando Nana said.

The raucous gathering is a security nightmare in a poor Southeast Asian country still battling Muslim extremists in the south and widespread crimes. Police sharpshooters stood by and surveillance drones were flown over the slow-moving procession.

More than 100 people fainted or got bruised in the initial hours while jostling through the thick crowds to get close to or have their white towels wiped on the wooden statue of Christ, which was on a carriage pulled by a rope by men in maroon shirts, according to the local Red Cross.

The wooden statue of a Christ, crowned with thorns and bearing a cross, is believed to have been brought from Mexico to Manila on a galleon in 1606 by Spanish missionaries. The ship that carried it caught fire, but the charred statue survived. Some believe the statue's survival from fires and earthquakes through the centuries, and intense bombings during World War II, is a testament to its mystical powers.

The spectacle reflects the country's unique brand of Catholicism, which includes folk superstitions, in Asia's largest Catholic nation. Dozens of Filipinos have themselves nailed to crosses on Good Friday in another tradition to emulate Christ's suffering that draws huge crowds each year.

Mostly barefoot, the devotees from all walks of life brave the crowds and heat to pray for good health, jobs, fortune and solution to all sorts of predicaments.

Dante Avila, a 22-year-old factory worker, said he has been wrongly implicated in the shooting to death of a child in a gang brawl in November in his neighborhood in suburban Caloocan city. Fearing for his life, he said he fled from home and hid in a province and showed up at the procession to pray to the Nazarene to help him prove his innocence.

"I swear to God I'm innocent," Avila said from a stretcher in a first-aid station, where medics treated the injured.

After struggling to touch Christ's statue, he got crushed by the crowd and fainted.

Another devotee, Arvin Tamayo, and his family rented a truck to parade life-size statues of Christ and the Virgin Mary, a ritual they have been doing every year since his father died of cancer in 2009.

"We're praying for good health," he said. "It's so financially and emotionally draining to see somebody in the family die slowly in pain."
