The Aussie Actor took to social media to share that he was seeking refuge on a stairwell during the “brutal” attack.

Sheridan, who is staying in Tel Aviv, said everyone had been living life completely as normal just hours before the first attack.

“Life (was) completely normal in Israel. It was a big Jewish holiday yesterday, one week after new year,” he said via Instagram.

“I met a family who had 150 fly in for their wedding tomorrow. We were at a BBQ yesterday with young people who at this very minute are on their way to Gaza to fight.

“A few hours later, this country is at war. Their lives have completely changed in an instant.”

Sheridan said it was “unbelievable how quickly” the attack unfolded.

“My heart breaks. I’m in the stairwell so safe for now,” he said.

Albanese has described the surprise attack by the militant group as an “abhorrent attack on Israel”.

“This is indiscriminate. Civilians being targeted, killed and murdered, and as well, many of them being taken as hostages,” he told ABC’s Insiders program.

“Of course, people are worried about escalation, but Israel has a right to defend itself and it will be doing so.

“This has been a very dark 24 hours.”

Smart Traveller advises against any travel to Gaza, and for people to reconsider travel near the Israel border.

“There’s ongoing armed conflict in Southern Israel and Gaza. Rockets have been fired at Israel from Gaza,” the alert says.

“There have been separate terror attacks on civilians.”
