CAIRO (AP) — Pro-democracy protesters blocked roads in Sudan's capital with makeshift barricades and burning tires Tuesday, a day after the military seized power in a swift coup widely denounced by the international community.

The takeover came after weeks of mounting tensions between military and civilian leaders over the course and the pace of Sudan’s transition to democracy. It threated to derail that process, which has progressed in fits and starts since the overthrow of longtime autocrat Omar al-Bashir in a popular uprising two years ago.

The United Nations Security Council was to discuss the situation in a closed-door meeting later in the day.

Western governments and the U.N. condemned the coup and called for the release of Prime Minister Abdalla Hamdok and other senior officials, who were arrested Monday. U.S. President Joe Biden’s administration announced the suspension of $700 million in emergency assistance to Sudan, a nation in Africa linked by language and culture to the Arab world.

Mariam al-Mahdi, the foreign minister in the government that the military dissolved, was defiant Tuesday, declaring that she and other members of Hamdok's administration remained the legitimate authority in Sudan.

“We are still in our positions. We reject such coup and such unconstitutional measures,” she told The Associated Press over the phone from her home in Khartoum. “We will continue our peaceful disobedience and resistance.”

Hours after the military arrested Hamdok, Sudanese flooded the streets of the capital, Khartoum, and other cities in protest. At least four people were killed and over 80 wounded when security forces opened fire on protesters, according to the Sudan Doctors’ Committee.

The country and the world are now braced to see if more violence will unfold in the nation, which saw a bloody crackdown on pro-democracy protests in 2019. Some protesters remained in the streets of Khartoum and its twin city of Omdurman on Tuesday morning, with many roads blocked. A bigger test of how the military will respond to the resistance could come Saturday when protesters plan a mass march to demand a return to civilian rule.

Troops from the military and the feared Rapid Support Forces patrolled Khartoum neighborhoods overnight, chasing protesters. The international group Human Rights Watch said forces used live ammunition against demonstrators.

U.S. Secretary of State Antony Blinken called for an immediate halt to violence against protesters and for the restoration of internet services. He said the U.S. was coordinating with partners to “chart a common diplomatic approach to address these actions and to prevent them from leading to further instability in Sudan and the region.”

On Monday, Gen. Abdel-Fattah Burhan, the top military official in Sudan, dissolved the Hamdok government and the Sovereign Council, a joint military and civilian body created soon after al-Bashir’s ouster to run the country. He now heads a military council that he said would rule Sudan until elections in July 2023.

Burhan blamed quarrels and divisions among political factions for the military takeover. However, the coup comes less than a month before Burhan was supposed to hand the leadership of the Sovereign Council to a civilian, a step that would have decreased the military’s hold on power. In recent weeks, he repeatedly indicated he might not go through with that.

The general said he is serious about holding elections on schedule. But much could happen in the coming 19 months, and it is not clear if the military will be willing to release the grip it has had for decades.

Hamdok and others in the transitional government are still being held at a military camp outside Khartoum. Al-Mahdi spoke to the wife of one of those detained, Minister of Cabinet Affairs Khalid Omar, and said he was humiliated and mistreated during his arrest.

“They (military forces) took Khalid barefoot, wearing only his nightclothes,” she said.

The Sudanese Professionals’ Association, a group of unions which was behind the uprising against al-Bashir, urged people to go on strike and engage in civil disobedience. Separately, the Sudan Popular Liberation Movement–North, the country’s main rebel group, denounced the coup and called for people to take to the streets.
