SEVERAL hundred animal rights activists - some in their underwear - marched through the streets of Pamplona to protest at bullfighting on the eve of the Spanish city's wildly popular running of the bulls.

The protesters included three Huddersfield women.

Sisters Sabina and Tricia Arthur, of Milnsbridge, aged 24 and 20 , were joined by Huddersfield University student Gurj Bains, 19.
