Why Refugees and Migrants Are Moving West in the Cold and Rain

Travelers gathered in the rain waiting to cross from Croatia to Slovenia.

Here, a woman carrying a baby walked towards the border between Serbia and Croatia.

About 2,000 to 3,000 migrants and refugees were huddled in the rain when the gates were opened, the AP said.

Slovenian police had been sent to the border to stop an overwhelming number of people from pushing through.
