Muzychko played a key role in recent antigovernment demonstrations that led to the ouster of former President Viktor Yanukovych.

He was killed on the night of March 24-25 in the city of Rivne under unclear circumstances as police commandos attemped to detain him.

Muzychko was sought for organized-crime links, hooliganism, and threats to public officials.

On Thursday, hundreds of Right Sector supporters rallied outside the parliament building in Kyiv to demand that lawmakers investigate Muzychko's killing and consider the resignation of acting Interior Minister Arsen Avakov.

At least two individuals are facing charges after activists supporting Russia clashed with rival demonstrators in Georgia on Thursday.

Twenty-five activists of the Earth Is Our Home nongovernmental organization held a rally on Pushkin Square in central Tbilisi on Thursday to express support for Russian officials targeted by sanctions imposed by the United States after Russia annexed Ukraine's Crimea.

Some of the activists at the rally were carrying Russian flags. Dozens of opponents arrived at the site and provoked the clashes.

According to various sources, police detained two or three individuals, who were charged with hooliganism and resisting police.

They were released later on Thursday but asked not to leave Tbilisi as their hearings were scheduled for Friday.

"The responses of post-Soviet states (excluding the Baltics, which have also condemned Russia's actions) have been more mixed, reflecting the complex diplomatic environment and, in many cases, the imperative of retaining positive relations with Russia. Nevertheless, Russia appears to have received greater support in this crisis than after the war with Georgia in 2008, when no post-Soviet state joined it in recognising the independence of the breakaway territories of South Ossetia and Abkhazia. Privately, however, Russia's actions are likely to have caused alarm across the region."

Speaking at a military awards ceremony in Moscow on Friday, Putin thanked the commanders and service personnel of the Black Sea Fleet and other units based in Crimea for their service and courage.

He said the military had demonstrated its professionalism by avoiding provocations and preventing bloodshed during the process of Russia's internationally unrecognized annexation of the Black Sea peninsula.

He ordered Defense Minister Sergei Shoigu to begin handing over to Ukraine all military equipment and weapons belonging to units that have not joined the Russian military.

Shoigu said on Friday that all Ukrainian military installations in Crimea are under Russian control.

Moscow says Switzerland's decision to sanction Russia for its annexation of Crimea is "counterproductive."

The Russian Foreign Ministry said the penalties "ignore the realities and the explanations" given by Russian authorities about the situation on the Ukrainian peninsula.

Switzerland on March 26 imposed travel restrictions on a number of Russian officials, halted negotiations on a free-trade deal, and suspended weapons exports to Russia.

It also froze assets held by Ukraine's ousted former president, Viktor Yanukovych, and his entourage in Swiss banks.

The Moscow State Institute of International Relations (MGIMO), a diplomatic school with ties to the foreign ministry where Zubov has worked since 2001, said it had dismissed him for criticizing Russia's foreign policy.

A rock version of Ukraine's national anthem popped up on YouTube on March 24. The video featuring musician and Kharkiv EuroMaidan activist Nikita Rubchenko got some 300,000 views in just the first three days.

A new version of the "Ukraine Has Not Yet Died" ("Shche ne vmerla Ukrayina"), Ukraine's national anthem, includes guitar sound and drum beats.

"It was made to support the country and Ukrainian citizens," Rubchenko wrote on his Facebook page.
