KIEV (Reuters) - Russia is boosting its troop presence in eastern Ukraine and attacks from separatist rebels have intensified as they seek to gain more territory from government forces, the Ukrainian military said on Wednesday.
Kiev's forces confronted Russian regular troops at an army checkpoint just west of Luhansk after coming under attack there on Tuesday while fighting between government soldiers and the Russian-backed separatists raged on among the ruins of the airport in the city of Donetsk, a spokesman said.
