GENEVA, June 4 (Reuters) – Switzerland will deploy around 4,000 troops inside its territory to reinforce security as ​world leaders gather for the G7 summit ‌in neighboring France in mid-June, the Swiss army said on Thursday.

The June 15 to 17 summit, to be held across Lake Geneva in the French town ‌of ​Evian-les-Bains, will bring together leaders ⁠from the world’s ⁠major economies, including U.S. President Donald Trump, alongside other high-level delegations.

The scale of the event and its proximity to the Swiss border ​require close coordination between civilian and military authorities, the unit that plans and manages ⁠the Swiss Armed Forces ⁠said. Protests are anticipated.

“The proximity to ​the border presents a major challenge for security authorities ​in the cantons of Vaud, Geneva and ‌Valais. As a result, the Federal Council and Parliament have decided on a subsidiary security deployment of the army,” the Swiss army’s ⁠Defence Group said in a statement.

Military personnel will be tasked with protecting critical infrastructure, including Geneva Airport, ⁠bolstering border ‌surveillance, and monitoring key transport routes ⁠and Lake Geneva, it said.

Switzerland’s air ​force ‌will also step up air policing, ​with airspace ⁠restrictions in place from June 10 to June 19, and will provide counter-drone systems and protection against nuclear, biological and chemical threats, the statement added.
