A rainbow-coloured bench installed at the site of a deadly jihadist attack which targeted revellers at Berlin's Pride march in July has been vandalised, police said Tuesday.

Police were called to Berlin's Tiergarten park "regarding a rainbow bench installed as a place of remembrance, because it was severely damaged," police said, before the debris was removed.

The vehicle ramming and machete attack left a 65-year-old Polish woman dead and wounded around 30 people.

The presumed attacker, Abdul Rahman Ballout, a 21-year-old German man of Lebanese origin, was killed the next day by Berlin police after an intensive manhunt.

Prosecutors later said he had pledged allegiance to the Islamic State group in a video on the day of the attack.
