Hussein's son Jihad Hussein told AFP his father had been taken to a police station near the Old City. The Shin Bet, Israel's internal security service, said they were all Arab citizens of Israel who were unknown to the authorities.
But despite concerns that the new measures could slow movement and spark renewed tensions, police said they appeared to be working fine and that 200 people had already passed through.
On Friday, Israeli police said three Arab-Israeli suspects, whom officials identified as terrorists, opened fire at a group of police officers, killing two officers.
Iran censured the Israeli regime's recent move to shut down Al-Aqsa Mosque and cancel Friday prayers at the holy site, warning against the "dangerous repercussions" of such measures.
Palestinian worshippers on Sunday refused to enter the holy site for midday prayers after metal detectors and cameras were added to the compound's gates.
In statements ahead of his departure to Paris late Saturday, Prime Minister Benjamin Netanyahu said he had ordered metal detectors installed at the gates as part of new security measures to be introduced at the holy site, also revered by Jews as the Temple Mount.
Palestinian sources said that IOF were heavily depoloying at the gates of Al-Aqsa and preventing Palestinians from getting into the holy compound.
After Israel occupied East Jerusalem in 1967, Israeli authorities have maintained an agreement with the Islamic Endowment that runs the al-Aqsa Mosque compound.
Jordan's stance is that anything installed at the site must be approved by the Waqf, or Muslim administration, and can not change the status quo, said the official.
"We hold the Israeli government responsible for the changes they have made in the al-Aqsa Mosque and taking its control away from us".
The Tel Aviv regime has been trying to change the demographic makeup of Jerusalem al-Quds by constructing settlements, destroying historical sites and expelling the local Palestinian population.
In the past two years, Palestinians have killed 45 Israelis, two visiting Americans and a British tourist in stabbings, shootings and attacks using cars to ram into Israeli civilians and troops.
Israel says the site won't reopen before Sunday.
Their comments angered the Palestinians, with one of them throwing a bottle at the females.
It is located in east Jerusalem, occupied by Israel in the 1967 Six Day War and later annexed in a move never recognised by the global community. It is the third holiest site for Muslims after the Mosque which houses the Kaaba in Mecca and the Mosque of Prophet Muhammad in Medina.
