Hungary said late Friday it would lay on buses to take thousands of migrants walking towards Austria on the motorway to the border town of Hegyeshalom if they wanted.

"During the night, buses will be brought to Keleti train station and to the M1 motorway where transport to the Hegyeshalom border crossing will be offered to the migrants," Prime Minister Viktor Orban's chief-of-staff Janos Lazar told a press conference.
