Rival groups demonstrate in Cologne over New Year's Eve attacks

German police have used water cannon to disperse anti-immigrant protesters in Cologne.

Officials said the far-right Pegida demonstrators had been throwing missiles at the police, and refusing orders to pull back.

Counter-demonstrations were held by feminist groups over violence against women in the city, and left-wing anti-Pegida opponents.

The demonstrations come after a string of sexual attacks on New Year's Eve, which shocked the country, and were said to be carried out by men of North African and Arab appearance.
