The Arab League convened an emergency meeting in Cairo after Sudanese officials alleged that various drone attacks against targets such as Khartoum International Airport originated from Ethiopia’s Bahir Dar airport. The Sudanese officials also alleged that these attacks were linked to support provided by the United Arab Emirates to the paramilitary Rapid Support Forces (RSF).
Ethiopia rejected the allegations and counter-claimed that Sudan was supporting hostile elements linked to the Tigray People’s Liberation Front, which the latter denied. Similarly the UAE also denied the allegations.
Earlier in February, Reuters said that Ethiopia made a secret training camp for thousands of RSF fighters near the Sudanese border, allegedly with financial and logistical backing from the UAE.
I am not sure how reliable this other site is but they claim that mixed results came from the emergency meeting becuase the UAE rejected strong language directly mentioning Ethiopia or referring to external support. The meeting apparently did get language of condemnation of attacks against Sudan generically and that Sudan has a right to defend its sovereignty.
