The parents of an American student who was wounded in the Bondi Beach shooting massacre say their son came to Australia to volunteer and spread love.

Leibel Lazaroff was shot in the leg and abdomen and has undergone surgery.

He is one of 24 people who remain in hospitals across Sydney, including three in a critical condition.

Rabbi Yossi Lazaroff and Manya Lazaroff told 9News their son had only been in Australia for two months, at the invitation of Rabbi Eli Schlanger, who died in the attack, and had intended to volunteer, spread love and kindness, and share the message of his religion.

The couple began their trip to Australia the moment they heard news.

“Feeling a little helpless on the other side of the world in America,” Yossi Lazaroff said.

“We’re asking people to light in his honour, to light in his merit, for a speedy recovery.”

Earlier, the families of the two police officers injured during the shooting released a statement of support “to the loved ones of those who were killed and injured” in the massacre.

Constable Scott Dyson and Probationary Constable Jack Hibbert are both in hospital, with Hibbert undergoing surgery to his shoulder and eye at Royal Prince Alfred Hospital.

Dyson and Hibbert’s families shared their “heartfelt gratitude to all first responders who acted with courage, in particular the police officers and paramedics who responded”.

“They also wish to thank their hospital team, and especially those in ICU,” NSW Police said in a statement on Monday.

“They thank the community for their support but have asked for privacy as their loved ones focus on recovery and healing.”

NSW Health Minister Ryan Park said he had met with Hibbert’s family yesterday and praised his actions.

“He was extremely brave when everyone was running away,” Park said.

“He was essentially running towards where the incident was taking place and that’s an incredible level of bravery.”

Park added it was a “rough road ahead”, but that he was receiving world-class care.
