Ukraine's interim President Olexander
Turchynov is due to form a unity government, days after the ousting of
President Viktor Yanukovych.
Mr Turchynov has promised that his coalition
administration will be a "government of the people".
Meanwhile, senior Western diplomats are
continuing talks in Kiev with the interim leadership, as the US and UK are to
discuss emergency financial assistance, reports BBC.
The US has yet to endorse the new leader, but
says "Mr Yanukovych is no longer actively leading the country".
An
arrest warrant has been issued for Mr Yanukovych, who has disappeared.
Acting
Interior Minister Arsen Avakov said a criminal case had been opened against the
ousted president and other officials over "mass murder of peaceful
citizens".
Mr Yanukovych was last reported seen on
Sunday in Balaklava on the Crimean peninsula - an autonomous region where the
majority of the population is ethnically Russian.
Crimea
and some pro-Russian areas in the east have seen protests against the overthrow
of Mr Yanukovych, sparking fears that Ukraine could be split apart by
separatist movements.
Thousands of people remain in Kiev's
Independence Square, the Maidan.
