The Israeli military said on Monday that sirens sounded in central Israel after approximately five projectile launches were identified crossing from Lebanon into Israeli territory.
The military said some projectiles were intercepted, while the rest fell in open areas.
It added there were no changes made in the Home Front Command's guidelines.
Lebanon's Hezbollah later issued a statement saying they launched a missile operation targeting a military intelligence unit near Tel Aviv.
"A missile launch operation (was carried out on) the Glilot base of the military intelligence unit 8200 located in the suburbs of Tel Aviv," the statement said.
