US urges countries to help Ukraine’s economic rescue

US Treasury Secretary Jacob Lew has urged other countries to contribute more to the economic rescue of Ukraine.

He told the International Monetary Fund (IMF) that Ukraine’s “sizeable financing needs” meant other nations must add to its $1bn (£597m, 720m euros) loan guarantee.

The appeal came as Ukraine’s interim prime minister offered to devolve more powers to eastern regions.

Pro-Russian separatists there are defying the government.

Meanwhile, Washington on Friday announced a third round of sanctions against individuals it has linked to Russia’s annexation of Crimea.

The US Treasury said it had frozen the US-based assets of one former Ukrainian official, a Crimea-based energy firm and six Crimean leaders, including the chairman of the Crimea electoral commission and the mayor of Sevastopol.
