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

Now, solve this: Kiev, Ukraine (CNN) -- New clashes erupted in eastern Ukraine as the divided country prepared for presidential elections this weekend, raising the question of whether pro-Russian forces sought to disrupt the vote in a move that the United States and its European allies say would trigger tougher sanctions on Moscow. Russian President Vladimir Putin said Friday that his government would respect the will of the Ukrainian people in Sunday's vote, but added Russia would closely monitor events. In a speech to an international economic forum in Saint Petersburg, Putin also warned of a "dangerous civil war" underway in Ukraine following what he called a "state coup" carried out "with support of the West, the United States" that ousted the country's pro-Russian leader earlier this year.NEW: Pentagon official says small number of Russian troops pulling back from borderClashes reported in eastern Ukraine as election approachesRussia's President warns of civil war in Ukraine; says he will respect voters' willSeparatists and pro-Ukrainian militants clash near town of Karlivka
