EU leaders recommit to helping Kyiv

But talks on migrants on hold as Poland and Hungary refuse to reach consensus

European Union leaders meeting for their summit in Brussels have agreed on security commitments to Ukraine for "as long as it takes", but failed so far to find consensus on the contentious migration reform.

The Russia-Ukraine conflict, migration and the EU's China policy were among key topics discussed during the summit on Thursday and Friday.

"The EU and member states stand ready to contribute, together with partners, to future security commitments to Ukraine, which will help Ukraine defend itself in the long term," the 27 EU heads of state agreed in conclusions of the summit, with the first day of talks ending on early Friday.
