A German military barracks in Cologne-Wahn has been sealed off due to suspicions of sabotage.

Authorities, including police and military intelligence, are investigating potential contamination of the site's water supply.

Reports suggest a possible break-in, with a hole discovered in the perimeter fence.

Soldiers and civilian staff have been instructed not to use the tap water, and no additional personnel are allowed to enter the premises.

The barracks, which house several military and civilian units, including the German Defense Ministry's flight readiness, employ around 4,300 soldiers and 1,200 civilian staff.

The investigation is ongoing, with the site remaining under strict lockdown as authorities search for any suspects.
