U.S. civil rights leader Rev. Jesse Jackson has died aged 84, according to a Feb. 17 announcement by his family. The cause of death was not immediately revealed. Jackson, a Baptist minister raised in the segregated South, became a close associate of Martin Luther King Jr. and emerged as one of the most prominent black political figures of the late 20th century. He twice ran for the Democratic presidential nomination in the 1980s.

The second round of indirect nuclear talks between the United States and Iran ended in Geneva, Switzerland. Iran’s foreign minister says Tehran and Washington have reached an understanding on key principles. He says there have been positive developments compared to the previous round, adding that both sides will now work on draft documents and exchange them. He also cautioned that the progress doesn't mean an agreement will be reached soon.
