The banner, which said "Jerusalem -- supports legitimacy -- against the coup," was hung on a wall in Al-Aqsa plaza, greeting tens of thousands of Muslim worshipers who arrived at the Temple Mount for prayers Friday, Ynetnews reported.
It was unclear who hung the banner.
Meanwhile, the U.S. Transportation Security Agency issued an advisory to its employees, informing them on what they may observe during Ramadan, which began earlier this week, CNN reported.
In a statement issued July 2, the TSA said it has "reminded its security workforce that traveling passengers may be observed at various areas in the airport -- including security checkpoints or on aircraft -- engaged in religious practices and meditations during Ramadan."
Such practices include fasting, carrying prayer beads and whispering prayers on planes and in airports, the TSA told its workforce.
"Whenever the TSA is trying to create an environment of understanding, we welcome that," said Haris Tarin, director of the Muslim Public Affairs Council's Washington office. "At the same time, it highlights certain actions that can make the American Muslim population seem almost alien."
