Israel resumes airstrikes in Lebanon

Israeli troops met fierce resistance from Hezbollah guerrillas today as they crossed into Lebanon to seek tunnels and weapons after warning residents in a nearly 20 mile swath of the south along the border to flee.

Israeli warplanes battered south Beirut again a day after a wave of bombings killed as many as 70 people, according to Lebanese television, making it the deadliest day since the fighting began on July 12.
