The Israeli military said air defences responded to missile attacks from Iran on Thursday that, according to medics, left six people lightly wounded and caused some damage.
A spokesperson for Israel's Magen David Adom emergency medical service said paramedics were providing medical treatment to "six people who were lightly injured by blast effects", updating an earlier toll of two injured.
Earlier on Thursday, a spokesperson for MDA told public radio there was damage to several houses in the central city of Kafr Qassem, whose mayor, Haitham Taha, said it was caused by cluster munitions.
The military said Home Front Command rescuers were called to an impact site "in central Israel".
In three separate statements in around 90 minutes, the military said it had "identified missiles launched from Iran toward the territory of the State of Israel".
"Defensive systems are operating to intercept the threat," the statements said, followed by announcements that people were "now permitted to leave protected spaces in all areas of the country".
Air raid sirens wailed across central Israel, including in Jerusalem and Israeli settlements in the occupied West Bank, while blasts were heard in Tel Aviv after the latest warning.
The attacks came more than 14 hours after the military last announced incoming missiles from Iran.
Israeli emergency services said a rocket fired from Lebanon killed a man in northern Israel on Thursday, as Israeli forces fight Iran-backed Hezbollah across the border.
"In the Nahariya area, MDA teams have pronounced a man of about 30 dead and were treating a man of about 50 who is in serious condition," Israel's Magen David Adom emergency service said in a statement.
Central Israel came under fire overnight from Lebanon , where Iran-backed group Hezbollah claimed a series of attacks targeting military sites. Israeli media said six rockets were intercepted. Israeli soldier killed in south Lebanon An Israeli soldier was also killed in fighting in south Lebanon on Thursday, the military said, after the army announced it was conducting ground operations.
"Staff Sergeant Ori Greenberg, aged 21, from Petah Tikva, a soldier of the Reconnaissance unit, Golani Brigade, fell during combat in southern Lebanon," the military said.
In total, three Israeli soldiers have been killed in fighting in south Lebanon since Hezbollah drew the country into war by launching rocket attacks against Israel on 2 March to avenge the killing of Iran's supreme leader.
