Example input: For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years

He said the 'extensive, quite precise' nature of the attack, which killed at least 22 patients and staff, casts doubt on the United States' assertions that it was a mistake. Haunting new photographs from inside the scorched hospital show how its operating theatres, wards, bedrooms and hallways have all been destroyed by the attack, which allegedly lasted for more than an hour.At least 22 patients and hospital staff were killed when US airstrike hit the Doctors Without Borders (MSF) hospitalMSF's general director Christopher Stokes said the 'quite precise' nature of the attack 'does not indicate a mistake'He claimed hospital was fired on 'repeatedly' even though they provided its coordinates to 'all parties in the conflict'US initially said strike was necessary to protect US troops during firefight with Taliban but have since apologised
