TEXAS (AP) - A Mexican military helicopter landed in Texas by mistake.

U.S. Customs and Border Protection says the helicopter landed Saturday afternoon at Laredo International Airport after the pilot mistook the airport for a landing strip in Nuevo Laredo, Mexico.

Laredo Port of Entry spokeswoman Mucia Dovalina says customs agents checked out the helicopter's occupants and let them return to Mexico.

She declined to say how many people were on board or whether they were armed.

The Houston Chronicle reports this is the second time Mexico's military has crossed into Texas in recent weeks.

A convoy rolled across the international bridge at Donna in July.

More troops have been deploying in northeastern Mexico as the nation attempts to combat drug gang violence.
