Ukraine conflict: Government claims airport victory

Authorities in Ukraine say they have launched a "mass operation" against separatist rebels in the east of the country.

Officials report that they have reclaimed almost all the area in and around Donetsk airport - a claim which cannot be independently verified.

In Kiev, thousands of people attended a rally for 13 civilians who died in the east when their bus came under rocket attack last Tuesday.
