FRANKFURT, May 30 - Ukraine’s economy is showing “remarkable resilience” following Russian attacks on its electricity infrastructure, officials from the International Monetary Fund said Tuesday as they signed off on an initial loan of $900 million and raised their estimate for the country’s economic growth.

The outlook improved to 1% to 3% growth this year from minus 3% to plus 1% in an earlier assessment in March, said Gavin Gray, the IMF’s mission chief to Ukraine, The Associated Press reported.
