"The resistance in Lebanon has all imaginable types of weapons," Nasrallah told the private Al-Mayadeen news channel in a Tuesday interview.

"We have weapons the enemy can't even conceive of," he asserted.

Nasrallah had previously warned Israel against exploiting the ongoing civil war in Syria – in which Hezbollah is involved – to strike Lebanon.

He also said that Hezbollah's missiles were capable of striking "every part" of the self-proclaimed Jewish state.

Last month, the local press quoted a Hezbollah source as saying that the Shiite group had detained a high-ranking group member – named Mohamed Shurba – who had been working for Israel's Mossad intelligence agency since 2007.

War erupted between Hezbollah and Israel in the summer of 2006. The conflict lasted 34 days, during which Hezbollah targeted major Israeli cities, including Acre and Haifa, causing significant material damage.

More than a thousand Lebanese were killed in the conflict, while much of southern Lebanon – a Hezbollah stronghold – was devastated by the Israeli onslaught.
