MOSCOW, April 18 (RIA Novosti) - The Foreign Ministry summoned the U.S. ambassador in Moscow Tuesday to hand him a note of protest against a seminar in Washington which it said called for new terrorist attacks in Russia.

"The organization of such events in the United States contradicts the country's international obligations in the sphere of counter-terrorism," the ministry said.

A seminar entitled, Sadullaev's Caucasian Front: Prospects for the Next Nalchik, took place in Washington on April 14 under the aegis of Jamestown Foundation, an American non-governmental organization. The Russian Foreign Ministry said the floor had been given to speakers who called for new terrorist acts in Russia.

"Such concessions on the part of Washington to Chechen militants and separatists also run counter to the spirit of partner-based bilateral anti-terrorist cooperation, and damage bilateral relations," the Russian ministry said.

In October 2005, at least 150 militants attacked administrative buildings in the city of Nalchik, the capital of the North Caucasus republic of Kabardino-Balkaria. Russian officials say that during two days of fighting, 35 law-enforcement officers and 12 civilians were killed. A total of 92 militants were killed and dozens captured.
