Brussel: European Union foreign ministers extended existing sanctions against Russia on Thursday, holding off on tighter economic measures for now but winning the support of the new left-leaning government of Greece, whose position had been in doubt.

The ministers agreed to extend until September travel bans and asset freezes imposed last year that had been due to expire. They also agreed to list the names of additional people who could be targeted with sanctions when they meet again on February 9.

They dropped language, however, about drawing up ‘further restrictive measures’ that had appeared in a pre-meeting draft. The bloc's foreign policy chief said a decision on such measures would be left to EU leaders meeting next month.

Germany said that decision would depend on the situation on the ground, with any major new rebel advance demanding tougher sanctions.

Thursday's emergency meeting had been called after rebels launched an advance last week, disavowing a five-month-old ceasefire. On Saturday, suspected rebel forces shelled the major port city of Mariupol, killing 30 people. Since then, there has been intense fighting along the frontline, although the rebels appear to have held back from an all-out assault on Mariupol.

Washington, which has coordinated sanctions moves with Brussels in the past year, said it was not planning an immediate new announcement itself.

The run-up to the Brussels talks was dominated by Greece, whose new prime minister, Alexis Tsipras, took power on Monday and complained that his government had not been consulted before tighter sanctions were threatened.

But at the meeting, colleagues said new foreign minister Nikos Kotzias had swiftly dispelled suggestions that Greece would automatically torpedo any sanctions effort.
