Tripoli's zoo is in urgent need of medical equipment and only has enough food for three weeks, a Bulgarian animal welfare group conducting a relief operation said on Wednesday.

Five weeks after rebels took the Libyan capital from forces loyal to Muammar Gaddafi, Vier Pfoten (Four Paws) said that there is a danger of a “crisis” at the zoo, home to more than 700 animals, unless more supplies are organised.

“We wish to thank all the organisations and people that have participated in providing food, but request that people and organisations and other NGO’s (non-governmental organisations) continue to assist,” the organisation said.

A team from Vier Pfoten visited the zoo in early September and returned earlier this week, bringing food, medicine and medical supplies donated or bought with donated funds. - Sapa-AFP
