Two killed in 'domestic violence incident' at school near Berlin

Two people have been killed in a "domestic violence incident" at a school in the town of Gosen-Neu Zittau near the German capital Berlin, local police have said.

Brandenburg state police said they arrested a 19-year-old German man, who is "considered a prime suspect". They said it was not a "mass shooting", without specifying what weapon was used.

It is not yet known if the suspect was a student at the private Docemus school.

One of the dead was an 18-year-old secondary school female student and the other victim was a 30-year-old man who died when he tried to intervene, local media reported.

The arrested suspect is believed to be the ex-boyfriend of the 18-year-old victim, Maz Online reported.

Ulrike Liedtke, the speaker of Brandenburg's regional parliament, called the incident a "cowardly femicide".

"The fact that we once again had to witness deadly violence against a woman fills me with deep sorrow and anger.

"I am shaken that a citizen who showed moral courage and wanted to help also lost his life in this terrible act," Liedtke said.
