European Union ambassadors will meet Wednesday to consider increasing the number of people hit with EU asset freezes and travel bans for their actions against Ukraine's government, an EU source and a Brussels diplomat say.

The ambassadors on Monday "agreed in principle to proceed with additional targeted restrictive measures," an EU source with knowledge of the meeting said.

A diplomat from one of EU's largest member countries said the envoys will meet Wednesday to consider a list of specific names. Some of the proposed sanctions targets may be Russian officials but the bulk will likely be leaders of the pro-Russia insurgency in eastern Ukraine, he said.

The EU source and diplomat spoke on condition of anonymity because they are not authorized to comment publicly on the sanctions issue.
