One person was killed and 27 others were wounded in a grenade attack at an entertainment center in Barrancabermeja, a city in northeastern Colombia, police said Sunday.
The attack occurred early Sunday in the Primero de Mayo district of Barrancabermeja, which is home to Colombia’s largest oil refinery, Magdalena Medio police chief Col. Ricardo Castrillon said.
Two unidentified men riding on a motorcycle threw the grenade at the establishment, “where one person died,” Castrillon said, citing eyewitness reports.
Police initially reported that 10 people had been wounded in the attack, but the Santander province Government Secretariat later raised the figure to 27, including two people who are listed in serious condition.
The wounded were treated at the Clinica La Magdalena and at Barrancabermeja Hospital, with the two seriously wounded individuals taken to Bucaramanga, the capital of Santander.
Officials, who are offering a reward of $5,400 for information leading to the arrests of the assailants, have not said who they suspect was behind the attack.
Revolutionary Armed Forces of Colombia, or FARC, and National Liberation Army, or ELN, urban guerrilla units operate in Barrancabermeja.
The Los Rastrojos and Los Urabeños gangs also operate in Barrancabermeja, which is on the Magdalena River, officials said.
Three attacks have now occurred in the past six weeks in Barrancabermeja, where state-controlled Ecopetrol operates Colombia’s largest oil refinery.
