"The FBI Joint Terrorism Task Forces conduct investigations into different groups that potentially pose a threat to the US or our interests overseas; however, the FBI and DHS have no specific intelligence about any group or so called sleeper cells planning an attack. Our job is to gather intelligence, work with our domestic and international partners to identify and disrupt any terrorism event," said Kolko.
Toronto has long been considered an important city for Hezbollah fund-raising and organizing, according to officials.
Pro-Hezbollah rallies and billboards depicting Hezbollah's leader, Hassan Nasrallah, have outraged Jewish groups.
"Because of lax immigration policies, it became a center for Hezbollah operations outside the Middle East," said Malcolm Hoenlein, of the Conference of Presidents of Major Jewish Organizations.
Hezbollah was declared a terror group by the government of Canada in December, 2002, leading to an increased surveillance of suspected members.
The last major attack by the terror group outside of the Middle East occurred in Buenos Aires, Argentina in 1994.
Argentinean authorities formally blamed Hezbollah and Iran for attacks on a Jewish community center that killed 85 people. Twenty-nine people died in an attack on the Israeli embassy in Buenos Aires in 1992 that was also blamed on Hezbollah and Iran.
As a political organization, Hezbollah, which means "Party of God," plays a significant role in Lebanese politics as the leading opposition force.
Founded in 1982, following Israel's invasion of Lebanon, the group came to represent Lebanon's Shiite population and has increased its power and influence in recent months.
