"Asking if Hezbollah is a terror organisation is like asking if Paris belongs to France," he told reporters late yesterday during a visit to France.
"Who is sleeping?" he said. "Are we Israelis sleeping or are countries in Europe sleeping? There's no debate."
The United States had asked the European Union to follow it and put Hezbollah on its terror list but the issue is contested among the 27 member states. A unanimous decision is required.
Israel and the Shiite militia, which is allied with the Iranian and Syrian regimes, fought a bloody 34-day war in 2006 that killed more than 1,200 people in Lebanon, mostly civilians. Some 160 Israelis, most of them soldiers, were killed.
Bulgaria has said Hezbollah was responsible for the bombing of an Israeli tourist bus in July last year which claimed six lives.
