Nigerian President Bola Tinubu on Wednesday lifted a six-month emergency rule in Rivers State, reinstating Governor Siminalayi Fubara and other officials, after saying that a constitutional crisis that had paralysed governance had been resolved.The emergency rule, imposed on March 18, followed a standoff between Fubara and the state legislature that disrupted budget approvals and left the government in limbo. Tinubu said the measure was necessary to prevent anarchy.Rivers State, located in the oil-producing Niger Delta, is an important hub for Nigeria's crude exports.
