BERLIN: The German government pledged on Sunday to fully investigate whether there were security lapses before the Christmas market car-ramming attack that killed five people and injured over 200.

Political pressure has built on the question of potential missed warnings about Saudi suspect Taleb al-Abdulmohsen, a 50-year-old psychiatrist who had made online deaths threats and previously had trouble with the law.

Interior Minister Nancy Faeser and the heads ofGermany`s domestic and foreign intelligence services are due to answer questions at parliamentary committee hearings on December 30, a senior lawmaker said.

Faeser vowed on Sunday that `no stone will be left unturned` in shedding light on what information had been available to security services ahead of last Friday`s bloody attack in the eastern city of Magdeburg.

Abdulmohsen has in the past called himself a `Saudi atheist` who helped women flee Gulf countries and charged Germany was doing too little to help them.

In online posts, he also strongly criticised Germany for allowing in too many Muslim refugees and backed far-right conspiracy theories about the `Islamisation` of Europe.News magazine Der Spiegel, citing security sources, said the Saudi secret service had warned Germany`s spy agency BND ayear ago about a tweet in which Abduhnohsen threatened Germany would pay a `price` for how it treated Saudi refu-gees. Die Welt daily reported, also citing security sources, that German state and federal police had carried out a `risk assessment` on Abdulmohsen last year but concluded that he posed `no specific danger`.

Blood and screams The city of Magdeburg has been in deep mourning over the mass carnage on Friday evening, when an SUV smashed through a crowd at its Christmas market, killing four women and a nine-year-old child and injuring 205 people.

Surgeons at overwhelmed hospitals have worked round the clock, and one health worker told local media of `blood on the floor everywhere, people screaming, lots of painkillers being administered`.

Scholz condemned the `terrible, insane` attack and madea call for national unity, at a time Germany is headed for early elections on February 23.

But as German media dug into Abdulmohsen`s past, and investigators gave away little, criticism rained down from opposition parties.

The far-right AfD called for a special session of parliament, and the head of the farleft BSW party, Sahra Wagenknecht, demanded that Faeser explain `why so many tips and warnings were ignored beforehand`.

Mass-circulation daily Bild asked: `Why did our police and intelligence services do nothing, even though they had the Saudi on their radar?...

And why were the tips from Saudi Arabia apparently ignored?` It charged that `German authorities usually only find out about attackplans in time when foreign services warn them` and called for sweeping reforms after the election for a complete `turnaround in internal security`.

Senior MP Dirk Wiese of Scholz`s Social Democrats said the De cember 30 hearings will summon the heads of the BND, the domestic intelligence service BfV and the Office for Migration and Refugees.

Media reported more details on Abdulmohsen, who had worked at a clinic that treats offenders with substance addiction problems, but had been on sick leave since late October.

Der Spiegel reported that in 2013 a court fined him for `disturbing the public peace by threatening to commit crimes` after he had darkly referenced the deadly attack on the Boston marathon.-AFP
