Edinburgh zoo closes panda enclosure to public in hope of rare birth of cub

Keepers are hoping the notoriously infertile bears can produce a cub at the third attempt after Tian Tian was artificially inseminated in March

The panda enclosure at Edinburgh zoo has been closed to the public as keepers hope for the arrival of a rare cub.

Britain's only female giant panda, Tian Tian, was artificially inseminated for the third time earlier this year. Experts said she had conceived, but they still do not know for sure if she is pregnant.
