<h1>Hundreds of thousands march across Europe in coordinated protests supporting Palestinians and aid flotilla, demanding pressure on Israel</h1> Hundreds of thousands marched across multiple European cities in coordinated demonstrations supporting Palestinians and an aid flotilla, with the largest gatherings in a major Turkish city and Amsterdam; protesters urged government action, economic and diplomatic pressure on Israel, and condemned what they described as ongoing 'genocide.' Rallies also marked the second anniversary of a 2023 attack that sparked the Gaza war, mourned victims of a recent synagogue attack in the UK, and demanded release of detained flotilla activists held by Israeli authorities. The events included flag burnings, election-related political pressure, and calls for humanitarian relief amid widespread accusations of unlawful conduct in the conflict.
