The Israeli military said it had struck several command centers belonging to Hezbollah, the Lebanese militia, south of Beirut on Monday morning.
Israeli officials said at least some were intercepted by Israeli missiles.
Israeli officials said Hezbollah had fired at least 250 projectiles, a term it often uses for rockets, into Israel on Sunday, including many toward Tel Aviv, with some causing injuries.
Analysts have said the intense attacks suggest that both Israel and Hezbollah are trying to maximize their leverage as diplomats conduct what they hope is a final round of cease-fire talks.
Amos Hochstein, a top American envoy, traveled to Lebanon and Israel last week to move talks ahead.
