(Reuters) - Russia on Wednesday told Ukraine to "watch out" after its former Soviet neighbour captured pro-Kremlin politician Viktor Medvedchuk, turning down Kyiv's offer of a swap with a warning that those holding him might soon be detained themselves.

Medvedchuk, one of President Vladimir Putin's close allies in Ukraine, was shown handcuffed and wearing the uniform of a Ukrainian soldier on Tuesday in a picture tweeted by President Volodymyr Zelenskiy.
