Rocket alarms that blared in Tel Aviv and other areas of central and northern Israel delayed the departure of US Secretary of State Antony Blinken, CNN reported on Wednesday morning.
Sirens had also sounded in Herzliya and Nazareth.
The IDF announced that it had intercepted two projectiles that had been fired from Lebanon into Israel, adding that the incident was under review.
The Israel Police later noted that it had received reports of shrapnel falling in Herzliya and Ramat Hasharon and that a vehicle had sustained damage.
No injuries reported
The Police noted that officers subsequently worked to cordon off the scene and that no injuries had been reported.
Israel's emergency medical response service, Magen David Adom, also stated that it had not received any reports of casualties.
Hezbollah later claimed responsibility for the attack, saying it had targeted the "Glilot base of the Military Intelligence Unit 8200 in the suburbs of Tel Aviv with a qualitative missile salvo."
This is a developing story.
