KIEV (Reuters) - Ukrainian President Petro Poroshenko said on Thursday he wanted next week's summit talks with German and French leaders to curb Russian "aggression" and force Moscow to comply with a February peace plan for east Ukraine.

Poroshenko made his comments at an awards ceremony to intelligence officers, as Kiev's military announced four more Ukrainian soldiers had been killed and 14 others wounded. The fighting threatens a six-month ceasefire between government forces and Russian-backed separatists.
