Police say masked gunmen opened fire on four luxury SUVs as they left the parking lot of an airport in northern Honduras, killing six men and wounding another three.
Police commissioner Julian Hernandez says the assailants were waiting for the men at La Mesa international airport in San Pedro Sula.
Hernandez says the victims have not been identified and most were in their 20s. Police are trying to determine the motive for the attack.
He says the victims were apparently also carrying weapons but police found none of them, perhaps because the assailants took them.
The attack took place Friday.
Authorities say Mexico's Sinaloa and Zetas drug cartels operate cocaine-trafficking routes in northern and eastern Honduras.
