Hezbollah could attack Europe at any time and with little to no warning, US State Department’s counter-terrorism coordinator Daniel Benjamin said Friday according to AFP, shortly after the US Treasury announced a fresh round of economic sanctions against the Lebanon-based terrorist group.

“Our assessment is that Hezbollah and Iran will both continue to maintain a heightened level of terrorist activity and operations in the near future,” Benjamin said at a conference call with reporters. “Hezbollah maintains a presence in Europe and its recent activities demonstrate that it is not constrained by concerns about collateral damage or political fallout that could result from conducting operations there… We assess that Hezbollah could attack in Europe or elsewhere at any time with little or no warning.”

The US Treasury stated that its new sanctions on Hezbollah were imposed due to the group’s continued support of Syrian President Bashar Assad. The move will freeze any assets Hezbollah may have under US jurisdiction and prohibit Americans and US companies from dealing with the Lebanon-based group.

The United States has already blocked Syria’s central bank and top Syrian government officials from US markets. On Friday, the administration also imposed sanctions on Syria’s state-run oil company Sytrol for having provided gasoline to Iran.

Benjamin warned that Hezbollah could become increasingly violent as international sanctions threaten Syria and Iran, its patron-states.  “Hezbollah believes there have been sustained Israeli and western campaigns against the group and its primary backers Iran and Syria over the past several years and this perception is unlikely to change. Both remain determined to exact revenge against Israel and to respond forcefully to the Western-led pressure against Iran and Syria,” he said.

Though dispelling fears that Hezbollah could be active in the United States, Benjamin said that the group has “stepped up terrorist campaign around the world.”

“It’s a very ambitious group with global reach,” he said.
