Bob Geldof said German Chancellor Angela Merkel needed to channel a minimum of 700 million euros ($947 million) in aid to Africa this year in order to meet a commitment signed by her predecessor Gerhard Schröder at the G8 summit in Gleneagles, Scotland in 2005.
"We are only asking what the politicians promised, not one euro more," the founder of Live Aid said at a press conference in Berlin on Tuesday.
"Schröder signed in the name of the German people, if Merkel betrays the pride of Germany, then she kills people 12 miles south of Europe in Africa," he said.
German music star Herbert Grönemeyer, who will sing at a major concert in Rostock on June 7 along with Bono and other musicians, said "politicians should just do their job and keep their promises."
