MANILA, Philippines — Millions of Roman Catholic devotees paraded with a statue of Christ through the Philippine capital under a massive police cordon Monday after the president warned that terrorists might target the raucous annual procession.

The government did not have specific intelligence on a terrorist plot. Still, about 15,000 policemen, backed by hundreds of army troops, secured the three-mile (five-kilometer) procession route for the charred wooden Black Nazarene statue from seaside Rizal Park to a popular church in Manila’s congested Quiapo district.
