A car bomb exploded as the president of the troubled Russian region of Ingushetia passed in his convoy Monday morning, critically wounding him and killing several others, officials said. Yunus Bek Yevkurov was the third top official to be wounded or killed in Ingushetia in the past three weeks and the fourth in Russia's turbulent North Caucasus this month. The explosion occurred around 8:30 a.m. (0430 GMT) as Yevkurov traveled outside the Ingush regional center Nazran, said Ingush Interior Ministry spokeswoman Madin Khadziyeva. He was hospitalized in unknown condition, she said. Federal Emergency Situations Ministry officials said he was in critical condition.
