Mexican authorities say armed men have abducted multiple people from an upscale restaurant in the popular beach resort city of Puerto Vallarta.

Prosecutors in the western state of Jalisco say two SUVs carrying an unknown number of gunmen arrived around 1 a.m. at the restaurant on the city's main boulevard, which runs through the hotel zone.

The Jalisco prosecutors' office said Monday in a statement that it was still investigating. Five vehicles were abandoned at the restaurant, but it was unclear whether they belonged to any of the victims or attackers.

Mexican media reports say as many as 16 people were abducted, but authorities did not immediately confirm the number.
