Paradise FM was closed on orders allegedly given by the Communication and Information Ministry, presenter Andrew Gibba said.
The closure came hours after Paradise FM interviewed a spokesman of a coalition backing president-elect Adama Barrow, to whom President Yahya Jammeh has refused to cede power after losing theelection.
The closure followed those of Teranga FM, Hilltop FM and Afri Radio.
The authorities have not given an explanation for any of the closures.
The Gambia Press Union has expressed concern that the closures could signal a crackdown on independent media amid the country’s escalating political crisis.
Mr. Barrow has said he would take power onas mandated by the constitution, despite Jammeh having challenged the election results in court.
After more than two decades in power, Jammeh, 51, lost the election to Barrow, a former real estate agent who was little known even in Gambia before he announced his candidacy.
West African leaders were due to meet in Abuja today to discuss the crisis. (dpa/NAN)
