U.K. authorities said Tuesday that they were punishing Rwanda over its alleged support of the rebels who now control two major cities in eastern Congo. The measures include pausing direct financial aid that doesn't include support to the poorest Rwandans.

Britain on Tuesday said it would pause some bilateral aid to Rwanda and impose other diplomatic sanctions on Kigali over its role in the conflict in neighbouring Congo, a move Kigali termed "punitive".
