Images of cluster bombs and artillery strikes on Ukrainian cities have prompted the world¡¯s top war crimes prosecutor to launch an investigation, with the support of dozens of nations opposed to Russia¡¯s invasion.

Karim Khan, a British lawyer named as the chief prosecutor of the International Criminal Court (ICC) last year, said the crisis in Ukraine is a chance to demonstrate that those committing war crimes would be held to account.

¡°I think the world is watching. The world expects better,¡± Khan, 51, said on Thursday in his offices in The Hague, announcing he had dispatched an advance team of investigators and lawyers to the region.
