King Salman also said that the US move to shift embassy to Jerusalem is "illegitimate"
Saudi Arabia's King Salman on Sunday slammed Iran's "blatant interference" in the region and lashed out at the US over Jerusalem as Arab leaders met in the kingdom for their annual summit.
The 82-year-old monarch dubbed the Arab League meet the "Jerusalem summit" as he took aim at Washington's decision to recognise the disputed city as the capital of Israel and transfer the US embassy from Tel Aviv.

Saudi Foreign Minister Adel al-Jubeir however insisted Riyadh would maintain "strong, strategic" ties with Washington.
"There is no contradiction with having very strong strategic ties with the US while telling your friends where their policy should change," Jubeir said in response to a question by AFP.
