Egypt Sunday condemned attacks on Saudi Arabia's embassy and consulate in Iran following the Sunni kingdom's mass execution of dozens, including a prominent Shia Muslim cleric.

"Egypt condemns the torching of the Saudi embassy in Tehran and the Saudi consulate in the city of Mashhad in Iran," the foreign ministry said in a statement.

Saudi Arabia announced Saturday it had executed 47 men on terrorism charges, including prominent Shia cleric Nimr Al-Nimr and dozens of Al-Qaeda members.

Those executed include one Egyptian and a man from Chad. The rest are Saudis.

Egypt stressed the need for "respecting the inviolability of the premises of diplomatic and consular missions and the safety of personnel," the statement added.

At least 44 people were arrested late Saturday for storming the diplomatic missions in Tehran and Mashhad.
