Genealogists have made an error in compiling the family tree of Hillary Clinton and she is in fact linked to a poor Welsh mining family, an expert claimed As she kicks off her bid to enter the White House, Hillary Clinton could claim that her path to the presidency began some 160 years ago in the little-known Welsh parish of Ystradyfodwg – if she can pronounce it, that is. For while the US Democrat has previously spoken of her British ancestry, a definitive family tree has revealed her links to a poor mining community in the Welsh Valleys. Ystradyfodwg, pronounced Ust-rady-vod-ug, was the home of Mrs Clinton's great grandmother - a woman who showed a determination, similar to that of the former First Lady, to struggle through poverty and eventually emigrate to America with her family.A definitive family tree of Hillary Clinton reveals her Welsh ancestorsThey lived in a poor mining district called Ystradyfodwg, now RhonddaFamily emigrated to Pennsylvania where Mrs Clinton's grandmother Hannah Jones was born - one of four children out of 14 born to surviveHannah Jones then eloped with Hugh Rodham - Mrs Clinton's grandfather - to marry because his family probably disproved of her poor background

(CNN) The Syrian rebels' assault on regime-held parts of Aleppo keeps getting deadlier, with 84 people killed over the past three days, the Syrian military said Monday. The latest violence also wounded 280 people in western Aleppo, Syria's General Command of the Armed Forces said. Syrian rebels have intensified attacks on western Aleppo to try to break the regime's siege of opposition-held eastern Aleppo, which has been choked off from food, fuel and other necessities. The military said rebels fired more than 100 mortars and launched 50 rockets. It also accused rebels of using chlorine gas on civilian areas, saying there were 48 cases of breathing difficulties.Syrian rebels have stepped up attacks to try to break the regime's siege of rebel-held eastern AleppoA UN envoy says he's "appalled" by the number of rockets indiscriminately launched by armed opposition
