Prosecutors in Mexico say gunmen have kidnapped 22 Mexican tourists in the beach resort of Acapulco.
The prosecutor's office in the southern state of Guerrero said the group, who was from the neighbouring state of Michoacan, was abducted on Thursday.
Local media reported the tourists were looking for a hotel in the popular tourist spot when they were seized by gunmen.
The prosecutor's office said it did not know the motive for the kidnapping, or who was behind it.
Acapulco is the scene of a violent turf war between rival drug cartels.
Eyewitnesses said the kidnappers were driving cars with Michoacan number plates.
Michoacan is the power base for La Familia Michoacana, a violent drug cartel active on Mexico's Pacific coast, the BBC says.
A BBC correspondent says this is the first mass kidnapping to happen in the resort.
