Now It's "Internationally Illegal" To Pray?

INN reports:

Secretary-General Amr Moussa of the Arab League sharply criticized Sunday's visit by Jews who prayed on the Temple Mount in Jerusalem, Judaism's most holy site. Rabbi Yisrael Ariel, manager of the Temple Institute, led the group.

Moussa said, "For the first time since '67, Jews are holding prayers in Al-Aksa during Ramadan in violation of international law, and we condemn it." He called the prayer "a hard blow to the [Muslim -ed.] holiness of the place, with no connection to it being during the month of Ramadan or another day."

(In some Egyptian media outlets which I couldn't enter, I found this: "Moussa condemns storming Al-Aqsa by Jewish groups". And see here.)


This legal stuff is getting silly.

What international law is violated by allowing Jews to pray at their most sacred site?
