G7峰会领导人讨论对俄实行新制裁
Leaders of the G7 industrial nations meeting in Brussels say they are prepared to impose further sanctions on Russia.
参加G7峰会的各国领导人聚于布鲁塞尔，他们声称将对俄罗斯实行进一步的制裁。
A joint statement condemned Moscow for its "continuing violation" of Ukraine's sovereignty.
The G7 summit is the first since Russia was expelled from the group following its annexation（合并） of Crimea in March.
On Thursday, leaders are set to discuss the global economic outlook, climate change and development issues.
Although Russian President Vladimir Putin is not at the Brussels summit, he will hold face-to-face talks with some G7 leaders - not including US President Barack Obama - in Paris afterwards.
However, both Mr Putin and Mr Obama will attend a ceremony commemorating the 70th anniversary of the D-Day landings in France on Friday.
While in Poland on Wednesday, President Obama warned Moscow against what he called its "dark tactics" in Ukraine.
Diplomacy has intensified to try to resolve the biggest crisis in years between Russia and the West, says the BBC's Chris Morris in Brussels.
