Russian President Vladimir Putin have voiced concern after award-winning Russian investigative journalist Yelena Milashina was attacked and hospitalised with injuries while on a work trip in Chechnya. Milashina had her head shaved and green dye poured on her, and her fingers were broken in the attack.

It remains unclear who the assailants were, though the journalist believes it is related to her investigative reporting that included exposing the alleged torture and killings of gay people in Chechnya and other abuses by feared Chechen paramilitary forces.

Chechen leader Ramzan Kadyrov said those responsible for the attack should be identified, while Putin’s spokesman said all appropriate actions are being taken for a full investigation into the attack.
