Live: Air strike launched on Ukraine military base near Polish border

Live news updates: An air strike was launched on a Ukrainian military base Yavoriv in the west of the country near the Polish border, the Lviv regional military administration said on Sunday. "The occupiers launched an air strike on the International Center for Peacekeeping and Security. According to preliminary data, they fired eight missiles," the administration said in a statement.

The centre, less than 25 km (15 miles) from the Polish border, did not say whether it had been hit. It said it would release details later, Reuters reported. 

The Congress Working Committee or CWC, the party's decision-making body, will meet at 4 pm Sunday, four days after a defeat in state polls, and is likely to advance internal elections scheduled in September amid renewed questions about its leadership, said media reports.

The Congress lost Punjab, one of the last major states where it held power, to the Aam Aadmi Party (AAP) and it was disappointed in its efforts to return to power in Uttarakhand, Goa and Manipur.
