The Palestinian flag was flown near the Reichstag in Berlin instead of the German flag.
According to the German media, three activists brought and installed a huge Palestinian flag instead of the German flag.
The fire department that arrived at the scene removed the activist who hung the flag from the mast, and the police detained him and two supporters in the area.
It was reported that the three activists were German citizens born in the country, they are 20, 22 and 32 years old. All three were released as soon as their information was received.
The German flag near the Reichstag is a national monument, the flag of unity, symbolizing the unification of Germany - it was raised for the first time on the night of October 3, 1990, when the country's unification took effect.
According to Bild, the pro-Palestinian group Peace Against People claimed responsibility for the flag rally near the Reichstag building.
It positions itself as a movement of non-violent civil resistance. Opposes the supply of German weapons to Israel.
Last year, activists of this initiative wrote the names of dead Palestinians on the asphalt of the red city hall in Berlin, hung a pro-Palestinian banner on the Brandenburg Gate and painted inscriptions on the Chancellor's office building. This year they blocked the entrance to the Rheinmetall factory in Berlin, and in July they participated in a protest against the concern together with Greta Thunberg.
