The Qatari Ministry of Foreign Affairs said its embassy in Khartoum was stormed and pillaged by what they described as "irregular armed forces".

"The State of Qatar condemns in the strongest terms the storming and vandalism of its Embassy building in Khartoum by irregular armed forces," the ministry said in a statement: assuring that no staff nor diplomats were harmed.

Furthermore, Qatar demanded that the attackers be prosecuted for their heinous crime which violates international law, and demanded that diplomatic missions be spared from the ongoing violence.
