Human rights activists in Chechnya say that masked men bashed their way into the group's office, sending the occupants fleeing through the windows.

The Committee against Torture wrote on its Twitter account on Wednesday that several young men, wearing surgical masks and armed with crowbars, attacked the group's office in the capital of Grozny. The employees escaped through the windows, the group said.

The Committee against Torture is a leading and one of the few remaining human rights groups operating in Chechnya, governed by Kremlin-backed Ramzan Kadyrov.

The group has aroused Kadyrov's ire before when it openly blamed him for persecuting the families of those who joined anti-government militants.
