Khartoum, Apr. 18: A US Embassy convoy came under fire in Sudan, Washington's top diplomat said Tuesday as he stepped up efforts for a cease-fire between the country's two top generals. Still, forces of the two rivals pounded each other for a fourth day with heavy weapons in the capital of Khartoum.
The attack on the convoy in Khartoum, along with an assault on the EU envoy's residence and the shelling of the Norwegian ambassador's home, signaled a further descent into chaos in the fighting. Millions of Sudanese in the capital and in other major cities have been hiding in their homes, caught in the crossfire as the two forces battle for control, with each general so far insisting he will crush the other.
The convoy of clearly marked US Embassy vehicles was attacked Monday, and preliminary reports link the assailants to the Rapid Support Forces, the paramilitary group battling Sudan's military, US Secretary of State Antony Blinken told reporters. Everyone in the convoy was safe, he said.
More than 185 people have been killed and more than 1,800 wounded since fighting began Saturday, according to UN figures, which did not include a breakdown of civilians and combatants. The Sudan Doctors' Syndicate said Tuesday that at least 144 civilians were killed and more than 1,400 were wounded.

The overall death toll could be much higher because clashes in Khartoum have prevented the removal of bodies in some areas.
The State Department said late Monday that Blinken spoke by phone separately with the two rival generals - armed forces chief Gen. Abdel-Fattah Burhan and RSF leader Gen. Mohammed Hamdan Dagalo.
"I made very clear that any attacks or threats or dangers posed to our diplomats were totally unacceptable," Blinken told reporters at the Group of Seven wealthy nations meeting in Japan on Tuesday,
He appealed for an immediate 24-hour cease-fire, as a foundation for a longer truce and a return to negotiations.
Dagalo said in a series of tweets Tuesday that he had approved a 24-hour humanitarian truce after speaking to Blinken.
The military said in a statement that it was "not aware of any coordination with mediators" on a truce and that more troops would join the battle. The fighting, it said, "entered the decisive phase," and that the coming hours would see a "crushing defeat" of the RSF.
More tanks and armored vehicles belonging to the military rolled into Khartoum early Tuesday, heading towards the military's headquarters and the Republican Palace, the seat of power, residents said. During the night, fighter jets swooped overhead and anti-aircraft fire lit up the skies.
Fighting resumed early Tuesday around each side's main bases and at strategic government buildings - all of which are in residential areas. Video from the Arab TV network Al-Arabiya showed a large explosion near the main military headquarters in central Khartoum that raised a giant cloud of smoke and dust.
Satellite images from Maxar Technologies taken Monday showed damage across Khartoum, including to security service buildings. Tanks stood guard at a bridge over the White Nile River and other locations in the Sudanese capital.
Satellite images from Planet Labs PBC, also taken Monday, showed some 20 damaged civilian and military aircraft at Khartoum International Airport, which has a military section. Some had been completely destroyed, with one still belching smoke. At the El Obeid and Merowe air bases, north and south of Khartoum, several fighter jets were among the destroyed aircraft.
The violence has raised the specter of civil war just as the Sudanese were trying to revive the drive for a democratic, civilian government after decades of military rule.
Each side already has tens of thousands of troops distributed around the districts of Khartoum and the city of Omdurman on the opposite bank of the Nile River. That has brought the fighting and chaos - with gunbattles, artillery barrages and airstrikes - to the doorsteps of the cities' terrified residents.
Residents have reported looting of shops and homes by fighters. One resident near Khartoum's Arabic Market area, said he saw a group of armed men in RSF uniform smashing doors of shops in the area and stealing goods including mobile phones. The paramilitary force denied the accusations and claimed that some people disguised as RSF troops and stormed residential houses.
The assaults on diplomats' homes were a further sign of a conflict running out of control.
The European Union's foreign policy chief, Josep Borrell tweeted Monday that the EU ambassador to Sudan "was assaulted in his own residency," without providing further details.
A Western diplomat in Cairo said the residence was ransacked by armed men in RSF uniforms. No one was hurt but the armed men stole several items, said the diplomat, who spoke on condition of anonymity because he was not authorized to talk to the media.
The RSF denied involvement in the attack, instead blaming the military. The military blamed the RSF, which grew out of the notorious Janjaweed militias in Sudan's Darfur region, for the attacks on the US convoy and the EU envoy's home.
Early Sunday, the Norwegian ambassador's residence in Khartoum was hit by a shell, Norwegian Foreign Minister Anniken Huitfeldt said in a statement. The hit caused damage but the ambassador was not injured, she said, adding that it did not appear the residence was intentionally targeted.
UN High Commissioner for Human Rights Volker Turk on Tuesday called for an immediate cease-fire and for the combatants to return to negotiations.
"Sudan has already endured so much pain and suffering. The fighting is born out of power games and personal interests that only serve to alienate the democratic aspirations of the population," Turk said in a statement.
Only four years ago, Sudan inspired hope after a popular uprising helped depose long-time autocratic leader Omar al-Bashir.
Burhan and Dagalo jointly orchestrated an October 2021 coup, derailing efforts to enshrine a civilian government. Both generals have a long history of human rights abuses, and their forces have cracked down on pro-democracy activists.
Under international pressure, Burhan and Dagalo recently agreed to a framework agreement with political parties and pro-democracy groups. But the signing was repeatedly delayed as tensions rose over the integration of the RSF into the armed forces and the future chain of command tensions that exploded into violence Saturday.-Agencies
