UEFA remains concerned over the lack of accommodation for fans and media in eastern Ukraine for Euro 2012, an official said Friday.

The Russian-speaking cities of Donetsk and Kharkiv have a deficit of thousands of hotel rooms required by European football's governing body of host cities, said Thomas Giordano, a UEFA spokesman.

"Accommodation in Donetsk and Kharkiv is not up to what we need. There are still hotels being built at the moment, and we are still working hard on finding additional accommodation in neighboring cities," he said at a sports media conference in Innsbruck, Austria.

Kharkiv is hosting three group matches, but Donetsk has five matches in total, including a quarterfinal and a semifinal.

UEFA regulations stipulate upwards of 5,500 hotel rooms for a semifinal venue.

Giordano said several contingency plans, including temporary camp sites, were being examined to deal with the influx of fans.

The continent's premier national team competition is in eight cities across Poland and Ukraine, starting in Warsaw on June 8 and ending with the final in Kiev on July 1.
