Jerusalem: Gaza militants fired more than 25 mortar shells toward communities in southern Israel Tuesday, the Israeli military said, in what appeared to be the largest single barrage fired since the 2014 Israel-Hamas war.

No one was hurt and the military said most were intercepted by the Iron Dome defense system. But the high volume of projectiles came as tensions have been running high along the Israel-Gaza border.

"A barrage of 25 mortar shells were launched towards several sites in Israeli territory. Most of the launches were intercepted by the IDF's (Israel Defence Forces) Iron Dome aerial defence system," the Iraeli military said in a statement.

Israeli media reported that one of the shells landed near a kindergarten shortly before it opened. Angry residents took to the airwaves to complain about how vulnerable they feel after 15 years of rocket fire threats from neighbouring Gaza, which will likely put pressure on the government to retaliate harshly.

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.
