The military said it had "identified missiles launched from Iran towards the territory of the State of Israel" for the first time in about 20 hours, with air raid sirens activated across central Israel.

Another warning of incoming missile fire came less than an hour later, prompting alerts across large parts of northern and central Israel, according to the military's Home Front Command.

"EMTs and paramedics are providing medical treatment and evacuating to hospitals 14 casualties", the Magen David Adom emergency medical service said in a statement, including an 11-year-old girl in a serious condition with shrapnel injuries.

It said a 13-year-old boy and 36-year-old woman, also with shrapnel injuries, were in moderate condition and a further 11 casualties in "mild condition".

It did not specify at how many sites people were injured.

Spokesman Zaki Heller had earlier told Israeli TV that at least 12 others were wounded as well as the 11-year-old girl.

Police reported damage at several sites in central Israel, sharing an image of what appears to be missile debris on a road.

Israeli media said cluster munitions, which explode mid-air and scatter bomblets across a wide area, were used in the attack.

Iran and Israel have previously accused each other of using cluster bombs.
