A suspect has appeared in court after an attack on a German Christmas market on Friday killed five people and injured more than 200 others.

The suspect, a doctor from Saudi Arabia, has been named as Taleb al-Abdulmohsen, who arrived in Germany in 2006 and was recognised as a refugee in 2016.

It comes as German authorities are facing increasing backlash after the alleged attacker used an access lane for emergency vehicles to drive into the market.

On a visit on Saturday, German Chancellor Olaf Scholz, ministers and regional political leaders were heckled by members of the public, some seemingly outraged by what was criticised as a lapse in security.
