Several hundred migrants stormed into Budapest's main international train station early Thursday after police re-opened it following a two-day standoff, an AFP reporter said.

In scenes of utter chaos, with the police seemingly entirely absent, hundreds of migrants tried to get on board the train, pushing, shoving and fighting with each other to get on.

A public announcement said however that no trains for western Europe would be leaving the Keleti station "for an indefinite period".
