At least 25 mortars fired from Gaza into Southern Israel
The Israeli military said more than 25 mortar shells have been fired from the Gaza Strip toward communities in southern Israel.
The military said most were intercepted by the Iron Dome defence system and no one was hurt in the barrage.
But the volume of mortars would appear to be the largest fired in a single incident since the 2014 Israel-Hamas war.
Israeli media reported that one of shells landed near a kindergarten shortly before it opened.
The border area has been tense in recent weeks as the Palestinians have held mass protests aimed at lifting a blockade imposed by Israel and Egypt after Hamas seized power in 2007.
Israeli fire has killed more than 110 Palestinians, most of them during the Hamas-led protests, which climaxed on May 14.
