A state of cautious calm prevails on Thursday on the battlefronts between the Sudanese army and the Rapid Support Forces in the capital Khartoum on the third day of the truce signed between the two parties, while Washington confirmed that it is closely monitoring the situation in Sudan and will discuss with the parties any violations that occur.

The ceasefire, which is being monitored by Saudi Arabia and the United States as well as the parties to the clashes, was reached after five weeks of fighting in Khartoum and violence in other parts of Sudan, including the western Darfur region.

Al Jazeera correspondents monitored warplanes flying over both the capital Khartoum and the city of Khartoum North, with ground anti-aircraft launched from some positions of the Rapid Support Forces south of Khartoum.

On Wednesday, Khartoum and Omdurman witnessed clashes between the two sides of the conflict in a number of locations.

For its part, the Sudanese army accused the Rapid Support Forces of violating the announced truce, saying that it had informed the sponsors of the agreement, but what it described as a rebel militia - a reference to the Rapid Support Forces - did not respond to any of the demands of the truce.

The army affirmed its commitment to maintaining the humanitarian truce without compromising its right to self-defense and the state, it said.

On Wednesday, a member of Sudan's Sovereignty Council, Lieutenant General Yasser al-Atta, accused the Rapid Support Forces of looting currency printing presses in Khartoum, seizing the state's stock of national currency and the Bank of Sudan's gold reserves.

On the other hand, the RSF accused the army of violating the humanitarian truce and bombing the positions of the Support Forces in several axes.

The RSF said it was committed to the declared humanitarian truce in appreciation of the humanitarian situation.

She called on what she described as putschists - in reference to the army - to abide by the humanitarian truce and respect the ceasefire agreement.

For its part, the Sudan Medical Syndicate announced on Thursday that the death toll among civilians has risen to 865, as a result of clashes between the army and the Rapid Support Forces since mid-April.

The syndicate reported that there are a large number of injuries and deaths that are not included in the count, as they were unable to reach hospitals due to the difficulty of movement in light of the current security situation.

U.S. Surveillance

In Washington, US State Department regional spokesman Samuel Warberg confirmed that his country is closely monitoring the situation in Sudan and will discuss with the parties any violations that occur.

Warberg added in an interview with Al Jazeera that the United States has the possibility of monitoring the ceasefire in Sudan via satellite.

Warberg also made clear that Washington is taking a step-by-step approach to the crisis in Sudan and that the priority now is to implement the truce and then extend it.

US National Security Council spokesman John Kirby said Washington's assessment of developments in Sudan suggested the ceasefire remained largely holding with some clashes.

Kirby said he was working closely with Saudi Arabia to facilitate differences, and with the international community on how best to monitor the ceasefire.

Chadian support

Politically, Sudanese Undersecretary of Foreign Affairs and envoy of the President of the Sovereignty Council Dafallah al-Haj praised Chadian President Mahamat Idriss Déby's cooperation with Sudan.

He stressed that he gave Déby an explanation on the latest developments in Sudan, and thanked him for his "wise decision to close the Sudanese-Chadian border to negative forces that harm the security and stability of the two countries."

Dafallah al-Hajj said – in a statement to Al Jazeera after meeting the Chadian president – that Déby stressed the need for the parties to respect the confrontations in Sudan for the truce.

For his part, the Chadian president affirmed his country's full readiness to provide everything necessary to restore security and stability in Sudan.

Déby expressed his country's regret over the current events in Sudan, stressing his country's "absolute" solidarity with him.
