Geneva: Thousands of anti-G7 protesters are expected to gather in Geneva on Sunday under heavy security, ahead of the Group of Seven summit set to take place in Evian, just across the French border.

The demonstration is being organised by the "No-G7" coalition, which brings together more than 60 unions, associations and left-wing groups. The alliance says it is protesting against "fascism and imperialism" as world leaders prepare for their annual three-day summit.

Authorities in Geneva are on high alert, fearing a repeat of violent scenes from 2003, when anti-G7 protests in the city led to widespread rioting, damage and looting. In response, several businesses, shops and institutions have boarded up their premises, while some events have been cancelled and the main hospital has set up emergency tents.

The Swiss authorities have approved a controlled protest march on a designated route on the northern side of the city, well away from the city centre and its luxury shopping districts. A substantial security operation is in place, with police deploying specialist equipment and personnel.

Geneva Security Minister Carole-Anne Kast said authorities were aiming to maintain order while allowing the demonstration to proceed under strict conditions. Meanwhile, coalition spokesperson Alice Lefrancois said organisers hoped for a peaceful and well-managed event with designated family areas and security support for demonstrators.

However, the planned counter-summit and protest in the nearby French town of Annemasse has been scrapped due to restrictions imposed by French authorities.

Tensions have also been heightened by broader geopolitical developments, with the summit taking place against the backdrop of rising international strain following recent conflicts involving the United States and Israel and wider tensions in the Middle East.
