Around 1.5 million devotees
The Black Nazarene, a life-sized wooden statue of Christ kneeling with a cross on his shoulder, is also paraded through the city on Good Friday to commemorate his crucifixion.
About 4,000 soldiers, police and emergency workers were on duty for he procession but police said there were no serious incidents.

Some Western governments had warned of "possible terrorist threats to the procession". Mobile telephone services in the area were cut and authorities banned the use of drones and firecrackers.

More than 100 devotees suffered minor injuries in the throng, the Philippine Red Cross said. In 2016, two people were killed and more than 1,200 people suffered minor injuries.
