Dutch authorities have said they are investigating reports of police violence against pro-Palestinian protesters after a banned rally on Wednesday evening had been broken up.

A total of 281 protesters were detained as they rallied in central Amsterdam on Wednesday in defiance of a ban imposed after violence stemming from a football match between Ajax and the Israeli club Maccabi Tel Aviv last week.

Detained protesters were put on buses and driven to a location on the outskirts of the city, where they were released.

A video circulating online, seen by Reuters, showed people being hit with batons by police in riot gear, seemingly while walking away after they had been released in the port area west of Amsterdam. The images could not be verified by Reuters.
