Argentina's foreign minister resigned on Friday due to differences with President Cristina Fernandez and was replaced by the Argentine ambassador to the United States, government sources said.
A Foreign Ministry statement said Jorge Taiana resigned because of "lack of support and differences" within the government over foreign policy decisions.
A ministry source told Reuters Taiana had an "argument" with the president, but said the reasons for his departure were not clear.
Fernandez's office said Taiana quit for personal reasons and his resignation had been accepted.
He will be replaced by Hector Timerman, a former journalist and Argentina's ambassador in Washington since 2007.
Taiana, a respected sociologist and human rights activist who was imprisoned under Argentina's 1976-1983 military dictatorship, was named foreign minister in 2005 by former president Nestor Kirchner and confirmed in the post two years later by his wife and current president Fernandez.
During his tenure, Taiana reasserted Argentina's long-running claim of sovereignty over the Falkland Islands, which Britain and Argentina went to war over in 1982. He issued a strong protest against British plans to begin offshore oil exploration in the islands called Las Malvinas by Argentina.
His successor Timerman is the son of Jacobo Timerman, a newspaper publisher who was imprisoned and tortured by the military in 1977.
Timerman was expected to take the lead on Argentina's claim that Iran was behind the 1994 bombing of a Jewish community center in Buenos Aires that killed 85 people. The unsolved probe into the attack is one of Fernandez's key foreign policy issues.
