MOSCOW (Reuters) - Two Russian Tu-160 nuclear-capable bombers rehearsed bombing runs in a training exercise in Belarus on Thursday amid tensions over a migrant crisis at the Poland-Belarus border, the Belarusian Defence Ministry said.

       It was the second day running that Russia has sent strategic bomber planes to overfly Belarus in a show of support for its close ally Belarus, which the European Union has accused of mounting a "hybrid attack" by pushing migrants across the border into Poland.
