CAIRNS: Eight children ranging from babies to teenagers were found dead at a home in the Australian city of Cairns on Friday, police said, reportedly in a gruesome mass stabbing just days after a deadly siege in Sydney.

Prime Minister Tony Abbott called the Cairns tragedy heartbreaking, with Australia already in an outpouring of national grief over Monday’s dramatic standoff in Sydney, which left two hostages and the gunman dead.

“All parents would feel a gut-wrenching sadness at what has happened,” he said in a statement. “This is an unspeakable crime”. Cairns police said they were called to the scene in the northern city and found the bodies of the children, aged between 18 months and 15 years.

A woman in her 30s, who police said is believed to be the mother of seven of the dead children, was injured in the incident in the suburb of Manoora, 10 minutes from the city centre. TV footage showed her being stretchered into an ambulance.

The victims have not yet been officially identified but police said that the eighth child is not from the same family group, as they said there were no formal suspects for the distressing deaths.

“We’re not talking about naming suspects or identifying particular suspects at this stage,” Cairns regional crime co-ordinator Detective Inspector Bruno Asnicar said.

“We’re looking at anybody that’s had any involvement. Everybody who’s had any involvement at all in the past two or three days is a person of interest”. Cairns is a tropical city with a population of more than 150,000 people and is popular with international tourists as a gateway to the Great Barrier Reef, one of Australia’s biggest tourist sites.

Only a day earlier, a Melbourne man was jailed for life for smothering to death his two daughters, aged three and four, in a move the judge said was aimed at punishing his ex-wife.

In the latest tragedy, the Australian Associated Press cited the injured woman’s cousin, Lisa Thaiday, as saying a 20-year-old man arrived home to find his siblings dead inside the house. “I just can’t believe it. We just found out (about) those poor babies”, Thaiday said.

Reports widely said the children had been stabbed while the Cairns Post reported they were also suffocated, although police did not immediately confirm this.Who killed the children remains unclear but Asnicar said there was no need for the public to be worried, suggesting no one was on the loose.

“As it stands there’s no need for the public to be concerned about this other than the fact that this is a tragic, tragic event,” he told a media conference.

“The situation is well controlled at the moment. There shouldn’t be any concern for anyone else out of this environment”.

He added that it was too early to determine the chain of events. “The crime scene is being locked down and that includes from me,” he said.

“Nobody goes in there until our forensic people have finished and until we have done that we’re not going to be able to clearly establish any relationships”.
