The Algerian presidency said in a statement late on Saturday that bin Salaman will not attend the summit in compliance with a doctors' recommendation to avoid travel.
Bin Salman, the kingdom's de-facto ruler, "expressed his regret for not attending the Arab summit", in a phone call with Algerian President Abdelmadjid Tebboune, the statement said.
The Saudi foreign ministry later issued a statement on the telephone conversation between the two leaders but did not mention that the Crown Prince was not attending the summit.
Arab heads of state are expected to convene for their upcoming 31st summit to be held in Algiers on November 1-2.
