Two policemen were wounded late on Tuesday night after unknown suspects opened fire on their patrol car in Russia's North Caucasus republic of Ingushetia, a local police spokesman said.
"Unknown suspects fired from a grenade launcher at a police patrol car at about 23:00 Moscow time [19:00 GMT] near the town of Malgobek. Two policemen were wounded as a result," the spokesman said.
He added that the policemen were taken to a hospital with one of them in grave condition.
This was the second attack on policemen in Ingushetia on Tuesday as earlier in the day a suicide bomber attacked a police post near the village of Galashki. The militant blew himself up but no one else was hurt in the attack.
More than a decade after the end of a war against separatists in Russia's North Caucasus republic of Chechnya, Russian security forces continue to fight militants in other regions in the area besides Chechnya, including Kabardino-Balkaria, Ingushetia, Dagestan, and North Ossetia.
Frequent attacks are staged on security forces, police and civilians.
