More than 1,000 scientists have petitioned the European Organisation for Nuclear Research (CERN) to take action over Israel’s war on Gaza, urging it to comply with its principles, including to “have no concern with work for military requirements”, Al Jazeera reports.

“As scientists, we firmly believe that international collaboration, the sharing of knowledge and the free movement of ideas are great drivers of human progress and peace. Middle Eastern scientists have remained steadfast in upholding these principles despite decades of regional tensions and conflict,” the petition read.

“As scientists, we cannot tolerate that the current state of war imposed by the Israeli government on Palestinians, alongside the unacceptable toll of lives and affront to human dignity, also compromises the continued peaceful collaboration of Israeli and Palestinian scientists between themselves, and with the rest of the community.”

CERN is home to the Large Hadron Collider, the world’s most powerful particle accelerator.
