The treatment of two elderly elephants at the Hanoi public zoo has drawn outrage in Vietnam, with animal rights groups demanding the pair be relocated.
The groups are calling for the two female elephants -- Thai and Banang -- to be released to a national park, and close to 70,000 people have signed an online petition in support.
Vietnamese state media have also covered the story widely in recent weeks.
