At least 260 people were killed at the festival in Israel on Saturday.
"We're still fighting - fighting back, basically," Richard Hecht, from Israel Defense Forces (IDF), tells BBC Breakfast.
The Palestinian Ministry of Foreign Affairs says Israeli air strikes have hit a United Nations school in Gaza.
The school housed hundreds of civilians, including children and the elderly, the ministry said, calling the strike "brutal".
The UN confirmed the attack, saying the school was "severely damaged". , externalNobody was killed, it added.
Our correspondent Anna Foster has just sent this from Ashkelon in southern Israel, which has been under rocket attack from Gaza.
The number killed by Israeli strikes on the Gaza Strip has risen to 493 people, the health ministry there has said.
The number of wounded Palestinians has also risen, to 2,751.
The United Nations says 123,538 people in Gaza have been internally displaced, mostly "due to fear, protection concerns and the destruction of their homes".
The Office for the Coordination of Humanitarian Affairs (OCHA) added that 73,000 people are sheltering in schools.
Adnan Abu Hasna - spokesperson for the UN agency for Palestinian refugees (UNRWA) - expects numbers to rise.
"There's electricity in these schools, we provide them with a meal, clean water, psychological support and medical treatment," he says.
There are 2.3 million Palestinians living in Gaza. Before launching its retaliatory air strikes on Saturday, Israel warned people living in certain areas to leave.
"I'm telling the people of Gaza: get out of there now, because we're about to act everywhere with all our force," Israeli Prime Minister Benjamin Netanyahu said on Saturday.
Israel's security tactics "collapsed totally" on Saturday, says a former head of one of their intelligence services.
Danny Yatom, ex-chief of the Mossad spy agency and politician from Israel's opposition Labor party, says "everything went wrong" and "nobody had a clue" on Saturday when Hamas attacked Israel from Gaza.
He tells the Today programme that Israel's second layer of defence was insufficient to stop the attacks, reminiscent of how Israel was caught flat-footed nearly "50 years and one day" from the Yom Kippur War, when a coalition of Arab states invaded.
Quote MessageThe amount of forces were too little - and this is mainly because of the failure of the intelligence that said that even though we witnessed many exercises by Hamas, they do not have any intention to [attack Israel]."
Volunteers searching for bodies at the Supernova music festival site - where at least 260 people were killed on Saturday - have had to suspend their search because they are “under fire” from militants.
Yossi Landau, a commander in the Zaka volunteer group, says his team of 25 have so far recovered 162 bodies from the site of the festival but “couldn’t get any further”.
“We work under fire, so had to evacuate that place,” Landau told the BBC's Today programme.
The 600-strong volunteer group, trained by the army, works to recover all the remains of victims for religious reasons, so that the individual can be buried “as he was alive”.
Footage from Saturday showed the festival-goers running as the attacks began.

We’re at a destroyed apartment building in Ashkelon, southern Israel, and have been speaking to 33-year-old Biana. She was at home last night when a rocket hit.
Quote MessageThe rockets started and the sirens started. We locked the door because there are terrorists around so we hid in the apartment. When the missile hit, we got stuck."
Biana
She says they were trapped for about 15 minutes before security could let them out. She said she was "very, very stressed and very, very scared”.
Her dog Lucky was barking after the missile landed. “I called him and said ‘everything is OK, you’re with me’,” she says, standing with the dog next to her former home.
She and her husband are now staying with neighbours but don't know what they will do in the longer term.
"They need to destroy the terrorists," she says.
In the last few hours, two senior members of the Israeli military have compared Saturday's attacks from Gaza to the 9/11 attacks on the US.
"This is our 9/11," spokesman Major Nir Dinar said. "They got us."
Lieutenant Colonel Jonathan Conricus also compared the hamas attacks to major attacks in America.
"This could be a 9/11 and and a Pearl Harbor wrapped into one," he said.
"It is, by far, the worst day in Israeli history. Never before have so many Israelis been killed by one single thing let alone enemy activity on one day."
More from that Israel Defense Forces briefing earlier.
A spokesman said "most" of the breach points on the barrier which separates Israel and Gaza have been closed, mainly with tanks.
But when pressed, the spokesman said he "couldn't deny" that militants may still be entering Israeli territory.
Thailand's foreign ministry says 12 Thai nationals have been killed since Hamas launched its attacks on Saturday morning.
Another 11 were kidnapped, and eight were injured.
One Thai worker told BBC Thai he was almost killed on Saturday.
"I was crawling underneath a truck then the Hamas [militant] pulled me out and pointed the gun at me," he said.
There are approximately 30,000 Thai nationals in Israel, and about 5,000 in the Gaza Strip.
More than 500 Hamas and Islamic Jihad targets in the Gaza Strip were hit overnight, says the Israeli Air Force (IAF), external.
The IAF says fighter jets and helicopters, aircraft and artillery struck the targets.
It also says it hit seven Hamas command centres and an Islamic Jihad command centre.
Palestinian health officials say 413 people have been killed in Gaza since the Israeli air strikes began.
At their morning briefing, the Israel Defense Forces (IDF) confirmed an Israeli family were still being held hostage by militants in Kfar Aza, which is near Gaza.
On Sunday, the Israeli government said more than 100 Israelis had been "kidnapped" - it's thought most taken into Gaza.
When asked about the number of hostages in Gaza, the IDF spokesman said: "I would say in the dozens."
Good morning.
If you are just joining us, here's a quick recap of what's been happening:
Stay with us and we'll keep bringing you updates throughout the day.
Israeli forces are still fighting Hamas gunmen at seven to eight sites in southern Israel close to the Gaza Strip, the Israel Defense Forces said in a briefing this morning.
These include Be’eri, an agrarian community, which was infiltrated by Hamas fighters overnight. Many of the militants have been killed, but others are still hiding in homes in the kibbutz, the IDF said.
The Israeli military added that it has attacked more than 1,000 targets in Gaza.
"The scope of this operation is something completely different... It’s taking more time than we expected to get things back to a defensive, security posture," Lt Col Richard Hecht told a briefing with journalists.

Poland has started evacuating its citizens from Israel, with the first plane carrying around 120 people landing in Warsaw early on Monday.
"The first people evacuated from Israel are already in Poland. I would like to thank [our] soldiers for carrying out the operation efficiently. You are the best," Polish defence minister Mariusz Blaszczak tweeted.
Two more planes are expected to arrive later in the day.
On Sunday, Mr Blaszczak said there were about 200 Polish tourists, including children on a school trip, waiting to leave Israel.
At least 200 Polish soldiers are assisting with the operation.
A Chinese-Israeli woman was among the people abducted by the Hamas militants at the Supernova music festival, the Israeli embassy in China said on their official, external social media account Weibo.
"She was forcibly dragged from Israel to Gaza," it added.
"Noa was born in Beijing. She's our daughter, sister, and friend."
The post included a video, without audio, which apparently showed Noa taken away by a group of men on a motorcycle.
Rescuers say they have recovered 260 bodies from the site of the music festival at the Negev desert, not far from the Gaza strip.
