A new prisoner swap between Ukraine and Russia has begun, officials in both countries said Monday, with Ukrainian soldiers who have spent nearly the entire duration of the war in captivity among those returning home.

The judge overseeing Harvey Weinstein's criminal case in Manhattan declared a mistrial on a rape charge on Thursday, one day after the former Hollywood movie mogul was convicted on a separate felony sex abuse charge.

Russia and Ukraine exchanged more prisoners of war on Tuesday, the Russian defence ministry said, without giving details of the numbers involved.
