More than 1,400 people, most of them civilians, were killed in Israel in the attack, during which Hamas took more than 240 people hostage, Israeli officials say. Israel in response has relentlessly bombarded Gaza and sent in ground troops.

Here are the key developments from the past 24 hours:

- Over 10,000 killed -

The Hamas-run health ministry said on Monday the death toll in Gaza had reached 10,022 people, after a night of heavy bombardment in the coastal territory.

The figure includes more than 4,000 children who have been killed, according to the ministry.

The United States acknowledged there have been "thousands" of civilian casualties in Gaza, after President Joe Biden had previously called the validity of numbers published by Hamas authorities into question.

"As it relates to civilian casualties in Gaza... we know the numbers are in the thousands," Pentagon spokesman Brigadier General Pat Ryder told journalists.

- Egypt evacuations resume -

The Rafah crossing between the Gaza Strip and Egypt reopened on Monday to allow the evacuation of foreigners, dual nationals and wounded Palestinians, the Hamas government said.

The terminal was opened for three days last week before closing over the weekend amid a dispute over the passage of ambulances.

Six ambulances arrived at the Egyptian side of the crossing on Monday carrying wounded Palestinians to be transported to hospitals, followed by the week's first group of dual nationals, an Egyptian border official told AFP.

The International Committee of the Red Cross said it had accompanied some of the ambulances, and the head of its Gaza office, William Schomburg, described "an immense relief to know that these patients are safe and will receive urgent medical care".

- UN chief says fighting must stop -

UN Secretary-General Antonio Guterres on Monday urged an immediate ceasefire and warned Gaza was becoming a "graveyard for children".

"The unfolding catastrophe makes the need for a humanitarian ceasefire more urgent with every passing hour," he told reporters at the UN headquarters.

"The nightmare in Gaza is more than a humanitarian crisis. It is a crisis of humanity."

The heads of 18 UN agencies said in a joint statement late on Sunday that 88 UN relief workers have been killed so far in the war.

- East Jerusalem, West Bank violence -

A Palestinian stabbed an Israeli border policewoman in annexed east Jerusalem who later died of her wounds on Monday, police said, adding that the assailant was shot dead after the attack.

Separately, the Palestinian health ministry said Israeli forces killed a Palestinian man in the town of Halhul and four in Tulkarem, both in the occupied West Bank.

- Activist arrest -

The Israeli army said on Monday it had arrested the prominent 22-year-old Palestinian activist Ahed Tamimi during a raid in the West Bank.

Asked about the reasons for her detention, a security source forwarded to AFP a social media post attributed to Tamimi that calls for the massacre of Israelis. The activist's mother, Nariman al-Tamimi, denied her daughter wrote the post.

The Israeli army on Monday said over 1,350 people had been arrested in the West Bank since October 7, including 850 allegedly affiliated with Hamas, while the Palestinian Prisoners' Club advocacy group put the number at 2,150.
