Mother 'collapsed in tears' on migrant march in Hungary
Hungary is to send buses to transport migrants to Austria's border after more than 1,000 began walking there earlier on Friday.
They left Budapest station on foot after a stand-off with police, defying official efforts to take them to reception centres and register them.
The BBC's Matthew Price was walking with those migrants in Hungary all day.
One woman told him she was trying to get to Germany to join her husband. She was "pushing a pushchair... also alongside her was a four-year-old boy and a daughter who was about six years old".
