Austria says it is planning to phase out special measures that have allowed thousands of migrants to travel freely from Hungary to Western Europe.Chancellor Werner Faymann said Austria would remove the emergency measures for asylum seekers "step by step".The easing of rules has meant thousands have been able to leave Hungary for Austria and Germany over the weekend.Germany, where most of the migrants are heading, warned that its willingness to help "should not be overstretched".The German interior ministry said the decision to allow migrants in over recent days was an exception and that the EU`s rules requiring asylum seekers to be processed in the first country they arrived in remained valid.Amid sharp disagreements among EU members, the UN`s Refugee Chief Antonio Guterres said the crisis was "manageable" if member states could agree a joint plan.Mr Faymann issued his statement after speaking by phone with German Chancellor Angela Merkel and Hungarian Prime Minister Viktor Orban on Sunday."We have always said this is an emergency situation in which we must act quickly and humanely," the Austrian chancellor said."We have helped more than 12,000 people in an acute situation. Now we have to move step-by-step away from emergency measures towards normality," he added.The change means that Austria will restore spot checks on those entering the country, as it had before the weekend. -BBC
