Another Kyiv update from our news desk:
European Union leaders on April 27 resisted Ukraine's demands for peacekeepers, as monitors reported a surge in shelling in the war-wracked east.
The EU did, however, agree to boost humanitarian support as Kyiv fights pro-Moscow separatists.
Observers from the Organization for Security and Cooperation in Europe (OSCE) say shelling continues on in the east despite a cease-fire deal signed in the Belarusian capital, Minsk, in February.
Ukraine's pro-Western President Petro Poroshenko called on the EU officials "to deploy an international peacekeeping mission in our country."
But Donald Tusk, the president of the European Council of EU leaders, said after the summit, "We know about Ukrainian expectations today, but it's impossible to send a military mission."
Tusk did say, however, that the EU would "send as soon as possible a civilian assessment mission."
The conflict between government troops and pro-Russian rebels has killed more than 6,000 people in the past year and displaced more than a million, according to the United Nations.
Poroshenko also called on the EU to consider Ukraine's bid to join the bloc, and said his country will be able meet conditions to apply for EU membership within five years.
