Although authorities have announced that the active phase of the counter-terrorism operation in the North Caucasus is over, violence continues to affect the region.
"During a detention attempt in the town of Malgobek on Sunday, the suspect was killed when he tried to throw an F-1 hand grenade," the spokesman said.
The republican interior ministry earlier said 40 gunmen have been neutralized in a special operation in Ingushetia since August 4.
"As a result of the operation, 23 active members of illegal armed formations have been detained, nine militants have been killed and eight gunmen have surrendered," the ministry said.
Through a partial amnesty announced on July 15, following the killing of the region's number one terrorist Shamil Basayev, militants not involved in major atrocities were promised leniency.
A law granting amnesty to militants and servicemen guilty of offenses during the North Caucasus antiterrorism campaign came into force in late September.
More than 300 militants have accepted the surrender offer since its announcement, mainly in Chechnya, according to Nikolai Patrushev, head of Russia's Federal Security Service (FSB) and the National Antiterrorism Committee.
