Austria pledged on Friday to improve appalling conditions at its refugee centres and admitted its current laws were insufficient to meet what Chancellor Werner Faymann described as "Europe's biggest challenge". Thousands of people from countries like Afghanistan or Syria have fled through the Balkans to Austria, pushing the number of asylum requests to 28,300 in the first six months of this year - more than the total for all of 2014.
