Hundreds of animal rights protesters have marched in protest against Oxford University's animal testing laboratory.

They rallied at Oxpens Meadow in Oxpens Road at 12.30pm before marching through the city centre to the Biomedical Sciences Building in South Parks Road, where a number of speeches were made.

Following the demonstration, campaigners returned to the city centre from the science area and are gathering in Broad Street before heading back to Oxpens Meadow.

Thames Valley Police officers on foot and on horseback are on stand-by.

But so far there has been no trouble at the gathering and organisers of the World Day for Animals in Laboratories said it was intended to be a peaceful protest.

Ellen Chambers, 60, from South Wales, said: "We don't need this old-fashioned experimentation any more."

Oxford University said earlier that it insisted on high standards of animal welfare in tests on animals, and almost all animals used in Oxford research are mice.
