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

Problem: "Trust needs to be rebuilt." That's what German Chancellor Angela Merkel firmly asserted early Friday -- as she had the previous day -- in the wake of reports the U.S. National Security Agency had eavesdropped on her cell phone. This claim and others that she and other world leaders have been spied on had "severely shaken" relationships between Europe and the United States, the German leader said.

Talk of the NSA's reported spying on Germany and other allies dominated Merkel's news conference in Brussels, Belgium. It illustrated the anger over this story in Europe and the challenges facing Washington because of it.U.S. official: "Surveillance capabilities, including with ... foreign partners" under reviewGerman leader: "True change is necessary" on part of the U.S.U.S. isn't monitoring Merkel's communications, White House insistsFrance is angry about claims the NSA intercepted millions of phone calls in France
