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

Q: (CNN) The Syrian regime has pounded the besieged city of Daraya with barrel bombs, just hours after food aid was delivered to the area for the first time in almost four years, officials and monitors said. The London-based Syrian Observatory for Human Rights said that at least 68 barrel bombs were dropped on Daraya on Friday as agencies delivered food rations to the city on the brink of starvation. This comes as the United States is leading airstrikes targeting ISIS extremists. The regime is bombing cities and towns trying to break away from government control, including the very groups armed by the United States to fight ISIS.20 people killed in suicide bombings68 barrel bombs dropped on DarayaFirst food aid delivery made in four years
