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

New input: Washington (CNN) -- Hindsight is 20/20, they say, but some people may need backwards-looking glasses in debating whether the State Department under Hillary Clinton erred two years ago by not designating Boko Haram a terrorist group. The question arose Thursday as part of the international focus on last month's abduction of more than 200 schoolgirls by the jihadist group in northeast Nigeria that threatens to sell them into slavery. A Daily Beast article raised the issue. It quoted an anonymous U.S. official who criticized the Clinton State Department for rejecting calls in 2012 by some in Congress, the Department of Justice and others to add Boko Haram to the terror list as a threat to U.S. interests and homeland security.Republicans criticize Hillary Clinton's handling of Nigerian jihadist groupUnder Clinton, the State Department didn't add Boko Haram to the terror listIt's not a cut-and-dried issue, argues a former State Department officialThe GOP attacks seek to weaken Clinton for her possible 2016 presidential run
