Palestinian militants in the Gaza Strip have fired more than 60 rockets towards Israel, after the Israeli military said it carried out a series of air strikes on Islamic Jihad rocket launchers.
At least two Palestinians have been killed in Gaza, according to health officials.
There are no reports of any serious injuries in Israel, where most rockets are said to have been intercepted.
This comes a day after 15 people in Gaza were killed in Israeli air strikes, including three Islamic Jihad leaders.
Israel’s prime minister said any escalation from militants would be met with a “crushing response”.
Palestinians said today’s exchange of fire began with several loud explosions in southern Gaza, sending up large plumes of smoke.
The Israel Defense Forces (IDF) said an aircraft targeted Islamic Jihad operatives travelling in a vehicle to a concealed rocket launcher in the Khan Younis area.
About an hour later, the IDF announced that it had started attacking underground rocket launchers belonging to Islamic Jihad across the territory in order to thwart planned attacks.
Palestinian media reported strikes in Gaza City, the northern town of Bait Lahiya, and the southern town of Rafah.
