Israeli army reports drone strike near Netanyahu's home

A drone launched from Lebanon has crashed into a building in the Israeli town of Caesarea, where Prime Minister Benjamin Netanyahu lives, Israel's military said on Saturday.

According to Israeli media reports, it was initially unknown whether Netanyahu was in the coastal resort located between Tel Aviv and Haifa at the time of the attack.

No one was injured in the incident, the army said. Two other unmanned flying objects were intercepted.

There was also an air alert in Tel Aviv, 55 kilometres to the south as a drone reportedly approached the Glilot district, where the headquarters of Israel's foreign intelligence service Mossad and another intelligence centre are located.

According to the army, sirens sounded in numerous other locations in northern Israel, including the city of Tiberias on the western shore of the Sea of Galilee.

The Lebanese Shiite militia Hezbollah, which is allied with Hamas in the Gaza Strip, has been firing rockets and drones at Israel almost daily since the start of the Gaza war in October last year.

Following the news of the death of Hamas leader Yehya al-Sinwar in Gaza, the Iranian-backed militia announced a "new phase of escalation."
