Sudanese Foreign Minister Maryam Al-Sadiq Al-Mahdi on Monday rejected any coup against the civilian government.
In televised statements, Al-Mahdi described the detention of Prime Minister Abdullah Hamdok as “dangerous” and “unacceptable”, saying his whereabouts is still unknown.
Early Monday, officials in Khartoum said the Sudanese military arrested Hamdok and members of his government.
The Information Ministry said Hamdok was arrested by a military force after he refused to support what it described as a "coup".
There was no comment from the Sudanese military on the developments.
Al-Mahdi expressed confidence that Hamdok will not bow to the military’s “dictates to dismiss the government."
"The partnership between civilians and the military faces a serious test," the top diplomat warned.
"There are no contacts between government ministers due to the interruption of communication and the closure of bridges," said Al-Mahdi, who confirmed reports that electricity and internet have been cut across the country.
Al-Mahdi said government ministers who were not detained will find a way to communicate and arrange matters in the coming hours, without giving further details.
