Russia detained five people and increased security in its northern Caucasus region after a bomb killed Akhmad Kadyrov, president of the Russian republic of Chechnya, Interfax reported. The identities of the five are being checked and it's premature to consider them the perpetrators of yesterday's attack, Interfax cited Ruslan Atsayev, a Chechen Interior Ministry spokesman, as saying. Russia has brought in extra search teams and placed security forces in the northern Caucasus on high alert.
