Cologne sex attacks: Women describe 'terrible' assaults

People gathering in front of the main railway station in Cologne, Germany, 31 December 2015

More than 100 women and girls have come forward with reports of sexual assault and robbery by gangs of men in the German city of Cologne on New Year's Eve.

Victims have described chaos outside the city's main station, as the men carried out dozens of attacks with little apparent response from the authorities.

Correspondents say the identification of the attackers as North African or Arab in appearance has caused alarm in Germany because of the influx of more than a million migrants and refugees in the past year.

Some of the women caught in the violence have begun speaking of their ordeal.
