Palestinian militants in the Gaza Strip have fired more than 30 rockets at southern Israel, Israeli officials say.
An Israeli military spokesman said eight hit urban civilian areas and that a number of others were intercepted by the Iron Dome missile defence system.
It was the heaviest barrage since the November 2012 conflict in Gaza ended.
The military wing of Islamic Jihad said it had fired the rockets in retaliation for Tuesday’s killing of three of its militants in an Israeli air strike.
“Our Mujahideen responded to the Zionist aggression by firing tens of rockets,” they said in a statement.
Speaking to the BBC, the group’s spokesman added “The rocket fired today came in response to the occupation aggression against us and does not mean the collapse of the ceasefire agreement [with Israel].”
Another Gaza militant group, the Popular Resistance Committees, said they fired several rockets as well.
