A fire that broke out in Liberia's presidential palace while President Ellen Johnson Sirleaf met there with other West African leaders was caused by faulty wiring, investigators said Sunday according to The Assocaited Press. The probe into a July 26 blaze at Sirleaf's offices in the war-battered capital, Monrovia, found no evidence of foul play, a top security official, Boimah Fahnbulleh, told reporters. Many Liberians were concerned that Sirleaf's enemies set fire to the building to endanger or embarass her as she met with Ghana's John Kufuor, Ivory Coast's Laurent Gbagbo and Sierra Leone's Ahmed Tejan Kabbah.
