One of Chechen separatist leader Shamil Basayev's supporters, a certain Abdulla Aliev, arrived at the prosecutor's office in Daghestan (a Russian autonomy on the western coast of the Caspian Sea bordering Chechnya) from Istanbul, said a source in the republic's government.
"He was an ideologist of Chechen extremism from Shamil Basayev's group," the source said.
