The officers were on a routine security patrol when an unidentified object exploded near the fence.

“This evening, at around 8.20pm, a serious security incident occurred at the fence” around the police building in the Wittenau district of northern Berlin, police posted on social media platform X.

One officer suffered injuries to the face and eyes, while the other experienced “sound trauma”. Both received medical treatment.

When questioned by AFP, a police spokesman declined to provide further information about the incident.

The explosion comes after 30 German law enforcement officers were injured on New Year’s Eve, including one seriously by an illegally manufactured firework.

Five people died across the country in incidents linked to the powerful fireworks Germans traditionally set off to celebrate the new year.
