MOSCOW, November 2 (RIA Novosti) - Seven police officers were injured after two bombs went off near a private house in the Republic of Ingushetia in Russia's restive North Caucasus region, a local police source said on Sunday.

A home-made bomb went off early on Sunday in the courtyard of a pensioner's house in the town of Ordzhonikidzevskaya in the Sunzha district. No one was injured in the blast, the police source said over the phone.

However, when a police squad arrived at the scene, a second bomb exploded, leaving seven police officers shell-shocked, the police source said.

Ingushetia has seen a rise in violence in recent months linked to separatists in neighboring Checnhya and internal power struggles.

On Monday, unknown assailants launched grenades and fired automatic weapons at a police official's home in the village of Inarki, Malgobek district, but no one was injured in the attack.
