Ukrainian officials have said they believe either Russian secret services or pro-Kremlin Chechen assassins were behind an attack on a Chechen man accused of plotting to kill Vladimir Putin outside Kyiv.
Adam Osmayev, who leads a battalion of Chechens fighting with Ukrainian forces in the east of the country, was wounded in the attack on October 30, and his wife Amina Okuyeva, who also fought in the battalion, was killed.
