SAO PAULO (AP) — Brazilian police say hundreds of thousands of evangelical Christians are taking part in Saturday's annual "March for Jesus" in Sao Paulo.

The Sao Paulo police department says on its Twitter page that the event has attracted at least 200,000 people and is expected to grow.

The event unites the faithful from hundreds of Protestant churches in Brazil, the world's largest Roman Catholic country.

In the past, the march has attracted as many as 1 million people. The Reborn in Christ Church that organizes the event has not estimated the number of participants.

The rally is expected to last well into the night.
