Europe violence as more migrants arrive

There has been more violence in Europe as police in Hungary used tear gas to disperse migrants protesting at a reception camp on the Serbian border.

Most of them are heading for western Europe, especially Germany.

The German Chancellor, Angela Merkel, says the current policies are not working and changes in policy are needed.

Last month more than 100,000 migrants arrived in Europe, mainly from Syria, Nigeria, Eritrea and Afghanistan.
