Israeli police have entered the area surrounding Jerusalem’s al-Aqsa mosque to break up stone-throwing Palestinian protesters.
Police poured into the disputed holy site in Jerusalem’s Old City, firing rubber bullets and tear gas.
There are reports that a number of protesters have barricaded themselves inside the mosque.
The protest was sparked by renovation work on Temple Mount, known to Muslims as the Haram al-Sharif.
Palestinians say it could damage the foundations of the compound.
The Israeli authorities say renovations are needed to safeguard the ancient site and have guaranteed that there will be no structural damage to the area.
