Australia's prime minister said the suspects in the shooting at the Hanukkah event were “motivated by Islamic State ideology.” They had traveled to the Philippines prior to the attack, officials said.

The Philippines Bureau of Immigration said on Tuesday that the two alleged gunmen behind the mass shooting at Sydney's Bondi Beach travelled to the Philippines on November 1 aboard Philippine Airlines Flight PR212 from Sydney to Manila and onward to Davao.

Investigators are probing a trip the father and son alleged to have carried out the attack took to the Philippines. The Sydney Opera House was lit up with a menorah overnight in a message of support and solidarity to the Australian Jewish community.

The death toll of the horrific Bondi terror attack has risen to at least 16 people, including a 10-year-old schoolgirl, with fears the number of victims will continue to grow. Sky News Australia has rolling coverage of the tragedy.
