Hezbollah said early Monday it had targeted an Israeli military base near the northern city of Haifa, the third attack on a military position in the area in one day.
Hezbollah fighters launched "a salvo of Fadi 1 rockets at the Carmel base south of Haifa," the Iran-backed group said in a statement.
Air raid sirens blared in Israel's north including the city of Haifa late Sunday night.
Earlier Sunday, the Lebanon-based militants said they carried out two attacks on another base also south of Haifa.
The group dedicated the attack to its slain leader Hassan Nasrallah, killed in an Israeli strike on the southern suburbs of Beirut last month.
Hezbollah is an Iran-backed Shiite political party and militant group in Lebanon.
It is designated as a terrorist organization by the US, Germany and several Sunni Arab countries.
