Ukraine ex-leader Yanukovych wanted by Interpol
Interpol has placed deposed Ukrainian President Viktor Yanukovych on its wanted list, almost one year after he fled to neighbouring Russia.
He is accused by Ukrainian officials of embezzling millions of dollars in public funds.
Mr Yanukovych was ousted after clashes between police and protesters in Kiev left dozens dead, mainly demonstrators.
Germany has stressed that a summit will only take place if it leads to “concrete progress”.
