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

Q: (CNN) US President Donald Trump has ordered the CIA to discontinue a program of arming and training anti-Assad rebels in Syria, according to a report in the Washington Post which cites unnamed US officials. The move is seen as controversial, given Russia's opposition to the rebels and Moscow's strong support for the regime of Syrian President Bashar al-Assad. "It's a strategic mistake.... (support for the rebels) was a pressure point on Assad and a pressure point on the Iranians... and the Russians," according to Bob Baer, CNN Intelligence and security analyst and former CIA operative. "It looks like, to me, that he just gave that as a gift to Vladimir Putin for no quid pro quo and that's not the way diplomacy works. We should've used this, we should've demanded, for example, safe zones so the Sunnis wouldn't get hit from the air... so this is just inexplicable, why he would do this.Kremlin says issue of US support for Syrian rebels didn't come up at Trump-Putin G20 meetingEnd of program wouldn't affect Pentagon's plans to support anti-ISIS rebel groups, report adds
