Gunmen burst into a bar in the Mexican border city of Ciudad Juarez and shot five men to death on Monday, state prosecutors said.
The victims ranged in age from 25 to 30 in the attack at Gabino's, located on a main boulevard of the city across from El Paso, Texas, said Arturo Sandoval, a spokesman for the Chihuahua state prosecutors' office.
Prosecutors have not established a motive in the killings. Six months ago, four men were killed in a shooting at the same bar.
Also Monday, soldiers arrested a suspect linked to at least 27 killings in Ciudad Juarez, the Defense Department said in a statement.
It said Eduar Vera, 30, told investigators he is a member of "La Linea," a group of hit men working for the Juarez drug cartel, and has personally killed at least 27 people in Ciudad Juarez and kidnapped 14 others that he turned over to be killed by a local street gang.
Drug-related violence has turned Ciudad Juarez into Mexico's deadliest city, with more than 1,700 killings so far this year.
In the southern state of Guerrero, gunmen killed two state police officers in the city of Iguala, the state public security office said in a statement Monday.
The officers were killed inside a command post. It was unclear what motivated the attack.
