Rwanda has put $1bn of global aid under threat by taking part in the invasion of the Democratic Republic of the Congo, the UK foreign secretary, David Lammy, has said.

He made the direct warning in a phone call to the Rwandan president, Paul Kagame, on Sunday after also speaking to the US secretary of state, Marco Rubio, about the crisis.
