GROZNY, Russia — It was supposed to be a night out. But for the young man who calls himself Maksim, as for scores of other gay men arrested in a pogrom this month in Russia’s Chechnya region, it pivoted into nearly two weeks of beatings and torture.

Maksim said it had started with a chat room conversation with “a very good old friend who is also gay,” and who suggested that they meet at an apartment. When Maksim arrived, however, he was greeted not by his friend but by agents who beat him. Later, they strapped him to a chair, attached electrical wires to his hands with alligator clips and began an interrogation.

“They yelled, ‘Who else do you know?’” Maksim said, and zapped him with current from time to time. “It was unbearably painful; I was hanging on with my last strength,” he added. “But I didn’t tell them anything.”

Gay men have never had an easy life in Chechnya. But the targeted, collective punishment of gays that began last month under its pro-Kremlin leader, Ramzan A. Kadyrov, is a new turn in the region’s long history of rights abuses.
