Two Palestinians have been killed and 200 wounded during violent protests in the West Bank against the continuing conflict in Gaza.

Approximately 10,000 people marched from Ramallah – which serves as the default capital of the Palestinian Authority - to East Jerusalem where they clashed with Israeli security forces in the Qalandiya area.

Israeli authorities say the protestors threw Molotov cocktails and rocks at police who responded with tear gas and rubber bullets.

Ramallah hospital claimed that dozens were being treated for live gunshot wounds, but Israeli officials would not confirm or deny whether live rounds were used.

Smaller clashes also took place in other parts of Jerusalem, including the Old City, the Mount of Olives and Palestinian neighbourhoods surrounding the city such as Silwan and Wadi Joz.

More protests are expected today on the last Friday of Ramadan. The date has also been used by Iran since the Islamic revolution to commemorate al-Quds (Jerusalem) day to show the regime’s solidarity with the Palestinian people.

Earlier, in his most strongly worded statement since hostilities began, UN Secretary General Ban Ki-moon said he was “appalled” by the Israeli attack on a UN school in Gaza which klled 15.

He also said he was “alarmed” to hear that rockets were being stored in the school and demanded a full investigation into the incident.

In a joint statement UK Foreign Secretary Philip Hammond and International Development Secretary Justine Greening said they were shocked by the reports of casualties at the school.

"International humanitarian law is clear that all feasible precautions must be taken to avoid harm to civilians during a military attack.

"Israel has the right to defend itself, but its response must be proportionate and it must do everything possible to avoid loss of civilian life," they said.
