[Hungary's State Secretary of the Ministry of Interior Kontrat, Austria's Interior Minister Sobotka, Austria's Defence Minister Doskozil and Czech Republic's Deputy Defence Minister Landovsky address a news conference in Vienna]More than a dozen countries in central and southeastern Europe agreed on Wednesday to draw up plans by late April for closer military and civilian cooperation to protect their borders in case a migrant deal the EU has struck with Turkey collapses.
