At least two opposition leaders in Russia’s republic of Ingushetia have been arrested on charges of attacking police shortly after being released from detention following protests against a divisive border-change deal.

Thousands took to the streets in Ingushetia last month over a land swap deal signed last fall with the neighboring republic of Chechnya in protests that occasionally turned violent. At least three organizers of the unauthorized protests — Akhmed Barakhoyev, Musa Malsagov and Barakh Chemurziyev — have each served 10 days behind bars.
