Argentine police arrested two Syrian and one Lebanese men on Tuesday who are suspected of planning to carry out a terrorist attack.
The three men, who had arrived separately in the country, were apprehended in Buenos Aires and in the adjacent suburb of Avellaneda.
A suspicious package originating from Yemen and weighing about 77 pounds was set to be delivered to the lodging where one of the suspects was staying, local media reported.
One of the Syrians had Venezuelan and Colombian passports in his possession.
Police are scouring the suspects’ cell phones on suspicion there may be additional operatives in their network, according to the media reports.
Buenos Aires is hosting the 15th edition of the Pan American Maccabi Games, with more than 4,000 Jewish athletes from 22 countries participating in the event.
Local police have been on heightened alert for the possibility of terrorist attacks.
The 1994 bombing of the AMIA Jewish community center in Buenos Aires blamed on Hezbollah killed 85 people and wounded more than 300 others.
Last month, a U.S. federal court indicted a Hezbollah leader who remains at large in Lebanon for assisting in the attack.
An earlier attack on the Israeli embassy in Buenos Aires in 1992 also attributed to the Islamist terrorist group killed 29 people and wounded 242 others.
