Edinburgh Zoo has said it believes its panda Tian Tian is pregnant and may give birth at the end of the month.

She was artificially inseminated earlier this year after attempts to bring her together with male partner, Yang Guang, failed.

Tian Tian also conceived last year, but the pregnancy failed.
