Israel's head of military intelligence says Hezbollah guerrillas in Lebanon should be wary of another war with Israel.

Marking 10 years since the monthlong 2006 summer war with Hezbollah, Maj. Gen. Herzi Halevi says Wednesday that Israel is more prepared than ever and that Hezbollah would suffer a great deal if it initiated another battle.

Speaking at the Herzliya Conference, Halevi said that if Hezbollah chief Hassan Nasrallah "knew our abilities, our knowledge, our preparedness, he wouldn't risk another conflict."

The 2006 fighting killed about 1,200 Lebanese, including hundreds of civilians, and about 160 Israelis, mostly soldiers. Israeli airstrikes heavily damaged Lebanon's infrastructure, while Hezbollah fired several thousand rockets into Israel. Israeli officials say Hezbollah's improved missile arsenal is now capable of striking virtually anywhere in the country.
