The siege attempt, which was initiated by the Iraqi army against the Martyr Rûstem Cudi Refugee Camp under the control of the United Nations on 21 May, was protested in Aarau, in Switzerland.

Many Kurdish citizens participated in the action held in front of the Aarau Bahnhof, holding PKK flags and photos of Kurdish People's Leader Abdullah Öcalan. The crowd often chanted the slogan "Bijî berxwedana Maxmurê" in Kurdish and German.

Making a statement, Aargau Rojbin Women's Council member Şevin Batu said that “what the Iraqi army is trying to do is unacceptable. We can’t accept the attempt to surround Maxmur camp with iron wires with the support of the invading Turkish state and the KDP administration.”

Batu, who called on the appropriate institutions, especially the UN, to stop the siege attempt as soon as possible, pointed out that the siege had no legal basis. Batu said that the people of Maxmur were resisting day and night, and emphasized that they would support the resistance until the end. After the statement, the crowd chanted slogans to end the protest.
