BRASILIA, Brazil (AP) — The mayor of a major city in northern Brazil says authorities are having to deal with a sudden influx of people from Venezuela, which has been rocked by political and economic turmoil.

An emergency decree by Manaus Mayor Arthur Neto allows spending of emergency funds.

Neto says hundreds of members of the Warao indigenous group in Venezuela have set up camps in the Amazonian city of 2 million people. City hall says they've come looking for jobs as Venezuela struggles with shortages of food and other goods, as well as political protests.

Neto says Manaus is offering to bus the Venezuelans back to their homeland, which is about 430 miles (700 kilometers) to the north.

Camps of Venezuelan migrants also have appeared in another northern provincial capital, Boa Vista.
