The Israeli Defense Forces (IDF) say they have carried out over 500 attacks on "strategic targets of the terrorist organizations" in Gaza overnight.
Fighter planes, helicopters, aircraft and artillery forces attacked "many hundreds" of Hamas and Islamic Jihad targets, the IDF said on X, formerly Twitter. Both groups are listed as terrorist organizations in the EU and the US.
An Israeli military spokesperson was meanwhile quoted by the Reuters news agency as saying that Israeli forces were fighting Hamas gunmen at seven or eight points outside of Gaza.
"It's taking more time than we expected to get things back into a defensive, security posture," Lt. Col. Richard Hecht told a briefing with journalists.
