GUADALAJARA, Mexico, Feb. 12 (UPI) -- At least six people were killed Saturday and 37 wounded when attackers sprayed the entrance to a bar in Guadalajara, Mexico, with gunfire and lobbed a grenade.

The bar, called the Butler Club, is in the tourist district of Guadalajara, CNN said. Citing the Mexican news agency Notimex, CNN said gunmen opened fire outside the bar and threw at least one grenade inside.


Some news reports put the death total as high as 14.

Guadalajara, about 250 miles northwest of Mexico City, is the country's second-largest city and a major tourist destination. The city, known for its high-tech industry, large population of well-educated younger workers and low unemployment, has been selected as the host of the Pan American Games in October.

But the city has also seen a surge in violence, including kidnappings and roadblocks, since the death of Ignacio Nacho Coronel, a reputed cartel leader killed by the military last year.

The federal Attorney General's Office announced an investigation has been opened into the killings, Diario de Guadalajara reported.

CNN said at least two of the dead were believed to be foreigners, one from Colombia and the other from Venezuela.
