KIEV, June 29 – The Ukrainian Environmental Protection Ministry has suspended licenses of Britain's Regal Petroleum plc on development of oil and gas fields in Ukraine, Environmental Protection Minister Viktor Boyko said at a press conference on Tuesday.

"I've signed a decree on the suspension of Regal Petroleum's activities," the minister said.

Boyko said that the interagency working group for deposit use at the ministry made the decision on December 23, 2009, as the company had not observed Ukrainian law.
