Tigers make first public appearance

Three Sumatran tiger cubs, born in February in London Zoo, have made their first public appearance.

As the three cubs took their first careful steps into their new enclosure, their mother Melati watched on.

Zoo employee Tracey said: "I think they were a bit overwhelmed really as it's such a big space."

Staff there aren't yet sure whether the cubs are males or females but they're pleased with how they coped with their first venture outside.
