Those in the mosque stated that occupation forces shot rubber bullets at them, wounding three.
They added that a fire erupted in one of the mosque's windows as the Israeli forces threw bombs at the youngsters inside.
Around 1,180 settlers breached the mosque as a group known as Temple Movement called for increasing breakings into Al-Aqsa, on the pretext of the occupation government will close down the mosque starting Friday and lasted until the end of Ramadhan.
Extremist settlers are set on organising "Flags March" tonight in the old city of Aqsa.
Head of Liberation Organisation executive committee Hussain Al-Shaikh stated that the status quo grants Islamic Awqaf responsibility of managing, maintaining, building, as well as overseeing visitors coming into the mosque, adding that occupation forces supervising this is a blatant breach and an attempt to create a new reality.
