Q: 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) -- During the last four months, the people of Ukraine have been fighting for their freedom, independence and European path in a war started by Russia-backed terrorists and their accomplices. Ukrainian military forces suffer heavy losses in battles against terrorists equipped with the newest Russian weaponry. We've seen reports of the pro-Russian thugs shooting women and children, cynically calling it a "protection of the Russian-speaking population." The price we are paying to bring peace back to the regions of Donetsk and Luhansk in eastern Ukraine is too high. Ukrainian President Petro Poroshenko has proposed the decentralization of power as part of his peace plan. It means more freedom, more economic autonomy and more opportunities to use languages spoken in a particular community for every region.Pavlo Klimkin: With downing of MH17, price of peace in eastern Ukraine already too highKlimkin: Ukrainians know bitterness of loss, share grief with families of the deceasedHe says the guilty must be promptly punished
