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 August.

New input: (CNN) Russia said one of its airstrikes in Syria killed ISIS spokesman Mohammad al-Adnani -- a claim that a US official called preposterous. On Wednesday, Russia's Ministry of Defense announced it killed the terror leader on the ministry's official Facebook page. It said Adnani was one of up to 40 ISIS militants killed by a Russian bomber in Aleppo province. But a US defense official slammed Russia's assertion.

We conducted a strike that targeted al-Adnani. We are assessing the results of that strike."A drone controlled by the US targeted ISIS leader, US defense officials told CNNUS official: Russia's claim would be "laughable" if it weren't for "humanitarian suffering Russia has inflicted"Mohammad al-Adnani had urged lone-wolf attacks against countries launching strikes against ISIS
