British Prime Minister David Cameron has rejected a call by Argentina's president for Britain to give control of the Falkland Islands to Argentina. Cristina Fernandez de Kirchner wrote an open letter to the British leader accusing his country of colonialism. More than 30 years have passed since Britain and Argentina fought a 10-week war over the Falkland Islands, a British overseas territory in the southwest Atlantic Ocean, but their dispute continues. In an open letter published as an advertisement in two British newspapers, Fernandez accused Britain of having "forcibly stripped" the islands from Argentina in a "blatant exercise" of 19th century colonialism. She called for Britain to begin discussions over the islands' sovereignty and said Britain had breached U.N. resolutions urging a negotiated resolution.
