Security Minister Patricia Bullrich responded to the foiled attack on social media, sayingP: "We are going to get rid of each and every one of these criminals who intend to sow fear in Argentines and they will pay."
In January, Argentinian police arrested three people with Syrian and Lebanese citizenship suspected of plotting a terror attack.
The security ministry said seven members of the alleged group had been arrested.
During eight raids of homes connected to the alleged members police seized firearms, knives and electronic devices.
