An Israeli cabinet minister blamed Palestinians in Lebanon, not Shi'ite Hezbollah guerrillas -- with whom Israel fought a war in 2006 -- for firing the rockets.
"I think these are isolated incidents," Rafi Eitan, a senior minister in Prime Minister Ehud Olmert's government, said on Israel's Channel 2. "We expected this."
A Lebanese minister also said he doubted Hezbollah had fired the rockets, which came from an area controlled by U.N. peacekeepers and the Lebanese army, 3 km (two miles) north of the border. Hamas sources in Lebanon denied involvement.
