The body of the 18-year-old girl was discovered on Friday evening near Novy Enginoi, a village northwest of Grozny, the capital of the Russian North Caucasus republic. She was shot in the head.
The bodies of six women aged between 25 and 35 were found in the Grozny region on Wednesday, all of them shot in the head or chest.
The incidents have so far been considered as separate cases. But human rights advocates said the murders in this largely Muslim republic could have been committed in retaliation for the women's immoral behavior.
Many women in this region wear headscarves and are supposed to observe Islamic rules and Chechen traditions in their daily conduct.
Chechen President Ramzan Kadyrov condemned the killings earlier this week as an outrageous act. "The murderers' actions, whoever they are, cannot be justified by any traditions. Moreover, neither the Chechen people nor Islam have such kind of traditions," Kadyrov said.
