Malawi's government has decreed that all call-in shows to be shelved with allegation of "careless and unethical coverage" of unrest by some broadcasters following last month's disputed election.

The communications regulatory authority statement dated Friday followed days of protest between police and opposition supporters whose reported irregularities in the election narrowly won by President Peter Mutharika.

On Thursday the United States ambassador was apprehended in tear gas fired by police against protesters while she met with opposition leader and election runner-up Lazarus Chakwera. The U.S. has called for restraint.

The president in a national address Thursday night accused Chakwera and his Malawi Congress Party of trying to cause chaos.

Malawi's new statement warns broadcasters that call-in shows is capable to "incite the masses into violence" in the southern African nation.
