JERUSALEM — At least eight Israelis described as former military personnel are being investigated for drug trafficking in Colombia.

The men, who are also being investigated for money laundering and the exploitation of minors, have been monitored by police for the past year, Colombia’s prosecutor told local media on Sunday, the El Tiempo newspaper reported.

The Israelis, based in the Caribbean city of Taganga, say they are legitimate investors and their papers are in order. They also are accused of links to a group of drug traffickers called the “Los Urabenos,” which reportedly is part of a different investigation.

Phone calls among the suspects that were intercepted by police must be translated since they are in Hebrew, according to El Tiempo.
