Suspect confesses to killing refugee child while rescuers search for victims of deadly boat sinking

Berlin prosecutors said Thursday that a 32-year-old German man arrested in the disappearance of a 4-year-old Bosnian boy has confessed to killing the child after the boy's body was found in his car.

Prosecutor Michael von Hagen told reporters Thursday that the man, whose identity wasn't released, was turned in by his mother after she recognized him in video released by police. The video showed 4-year-old Mohamed Januzi leaving the central registration center for refugees in Berlin with an unidentified man on Oct. 1.

Police were interviewing the mother at her home when the suspect showed up there Thursday morning and confessed, telling police he had the child's body in the car.

Von Hagen said an autopsy is still being performed but it appears the boy was not "killed today or yesterday." He says there's no evidence the suspect had any xenophobic motive or any links to far-right groups.

Meanwhile, at least seven refugees are dead after a boat capsized off the eastern island of Lesbos. Authorities are still searching for more than 30 others.

The bodies of two children, a man and a woman were recovered from the sea Thursday, the coast guard said. The accident occurred in stormy weather Wednesday. Coast guards and local fishermen managed to rescue 242 people.

Nearly 1,000 people were rescued in 20 separate incidents off the eastern Aegean over the past two days, the Greek coast guard said. But at least 11, mostly children, drowned in separate incidents Wednesday.

The European Union has struggled to cope with the massive influx of refugees fleeing conflict in the Middle East, Africa and Asia. On Thursday, Hungary's foreign minister said the international community must significantly ramp up its fight against the Islamic State group in order to stem the flow of people.

“The less successful we are in combatting terrorism, the more migrants will come to Europe and the bigger challenge we will face,” Foreign Minister Peter Szijjarto said.

Szijjarto also called on the 28-nation European Union to establish a "European force" to help Greece protect its vast sea borders with Turkey, from which thousands of people cross daily into Europe.

In addition, he said the EU must give more financial aid to Lebanon, Iraq, Jordan and Turkey so they can better take care of the hundreds of thousands of Syrian refugees crossing their borders.

Earlier Thursday, Swedish firefighters extinguished another small fire in a house for unaccompanied refugee children, police said.

Police say an "inflammable liquid was poured in through a window" of the house and are calling the blaze arson. No one was injured.

In recent weeks, Sweden has seen a spate of arson attacks on asylum centers or buildings as an influx of refugees has surged. Swedish immigration officials estimate up to 190,000 asylum-seekers will arrive this year.

Sweden's national police said they are coordinating the arson investigations and will use helicopters with infrared cameras in an attempt to find suspects.

In neighboring Norway, immigration authorities were considering whether to follow Sweden's decision and longer publicize the location of refugee facilities.

In Slovenia, police say more than 100,000 refugees have entered the country in less than two weeks. More than 5,000 came in Thursday morning, bringing the total number since Oct. 16 to 102,757, police added.

Asylum-seekers hoping to reach Western Europe turned to crossing Slovenia after Hungary closed its border with Croatia with a barbed-wire fence.

Slovenia has warned it could also put up a fence along its border with Croatia. The small nation of 2 million has repeatedly said it cannot not cope with the mass influx.
