ALI-YURT, Ingushetia — Speaking softly through tears in her family's tiny home in the North Caucasus, Roza Yevloyeva apologized for her son's suicide bomb attack on Russia's busiest airport 3 1/2 weeks ago.
Magomed Yevloyev, 20, detonated explosives strapped to his body at Moscow's Domodedovo airport on Jan. 24, killing 36 people. Analysts say the attack was proof the Kremlin has failed to quell a bubbling Islamist insurgency along its south.
"We commiserate, and we extend a very big apology to the whole world," Yevloyeva told Reuters on Wednesday in her first interview with foreign press in the town of Ali-Yurt in Ingushetia.
"We are so ashamed, so bitterly sad. We really worry for all the people who died, whom he wounded," the 54-year-old school teacher and mother of four said between muffled sobs as she perched on her dead son's wooden bed.
Islamist leader Doku Umarov, who said he ordered the attack, has since threatened a year of "blood and tears" before Russia's 2012 presidential elections, saying he has dozens of suicide bombers ready to unleash on Russian cities.
Styling himself as the Emir of the Caucasus, Umarov wants to create a separate state with sharia Islamic law across the Muslim republics of the North Caucasus that he considers to be "occupied" territory.
The robust insurgency in Ingushetia — a sliver of land next to Chechnya, the site of two post-Soviet separatist wars that underpin the militant movement — underscores the threat.
Magomed's brother Akhmed, 16, and his sister Fatima, 22, have now been arrested and taken to Moscow for questioning. His third sibling is physically disabled and does not leave the family home.
Authorities say Magomed's arrested siblings helped him prepare his bomb. Now, in the ramshackle family home, heated by a single wood-fired stove and decorated with rugs on the walls, his mother laments losing three of her children.
"Night is the most horrible time for me, because I do not have my children near me. The beds are empty," said Yevloyeva, whose patterned hijab crowns her pale face.
"Each bed draws me close, as that is where my children slept. Probably every mother feels this way," she said, patting Magomed's bed, wedged in the tiny room where three of her children had slept.
After years of the Soviet Union suppressing religion, both regional Muslim leaders and rebels have enjoyed an Islamic revival over the past 20 years.
Experts say a potent mix of this Islamism, poverty and heavy-handed tactics by law enforcement agencies drives youths into the hands of the rebels.
When asked what drew her son to Islamist extremism, Yevloyeva said she "did not educate him that way."
"We have Russian, Ingush and Chechen friends. … We treat everyone as one family, as we do with everyone in the world."
