Egypt President Mohammed Morsi has condemned Tuesday's deadly attacks on the U.S. consulate in Benghazi, Libya, and has vowed to protect foreign embassies in Cairo.

He made the pledge during a visit to the European Union Thursday.

The presidential condemnation comes after protestors climbed the walls at the U.S. Embassy in Cairo Wednesday. Protestors tore down an American flag and temporarily replaced it with a black, Islamist flag.

Morsi said the Egyptian people reject such "unlawful acts." He said he had personally spoken with President Barack Obama to condemn them "in the clearest terms."

According to The White House, Morsi promised that Egypt "would honor its obligation to ensure the safety of American personnel."

The president also told Morsi that while "he rejects efforts to denigrate Islam, there is never any justification for violence against innocents."
