[Updated at 7:17 p.m.] At least 15 people were killed in Ciudad Juarez, Mexico, Wednesday, as drug-related violence goes unabated, authorities said.
Police found seven young men killed in two locations in Juarez, police spokesman Jacinto Seguro told CNN.
Earlier Wednesday, eight men were shot to death outside a bar in what has become one of the country's deadliest cities, the state attorney general's office said.
It was the second violent day in a row that the city witnessed.
On Tuesday, 10 people were killed, Seguro said, including three who were shot outside a supermarket. Another victim, identified as Marin Orosco, was killed outside a mall hours later.
In all, 25 people were killed in a 24-hour period, Seguro said.
Ciudad Juarez is the most violent city in the nation, with more than 2,600 drug-related deaths in 2009. No official numbers are available for this year, but more than 400 killings have been reported by local media.
The city, long the focal point of President Felipe Calderon's battle against drug cartels, came to renewed prominence after the January 31 killings of 15 people, most of them students with no links to organized crime. The massacre sparked outrage throughout Mexico and drew worldwide attention.
In another incident that drew widespread attention, three people associated with the U.S. Consulate in Juarez were gunned down in two shootings last month. Two of the victims, including a pregnant woman, were U.S. citizens living in El Paso, Texas.
Arrests were made this week in the recent killings of federal police officers in Juarez, Seguro said. The suspects, members of the Juarez cartel, deny they were involved in the killings, he said.
[Posted at 3:04 p.m.] Eight men were shot to death early Wednesday morning outside a bar in Ciudad Juarez, Mexico, one of the country's deadliest cities, the state attorney general's office said.

Police were looking for a motive.
According to Chihuahua state police, the victims all had gunshot wounds to the head. Four of the victims were teenagers, three were in their early to mid-20s. The eighth man was about 40 years old, police said.
