In response to the attacks, the organisation appealed for respect for human rights and protection of civilian lives.

'The events of the past two weeks, in which about 100 people have their lost their lives and hundreds of others have been injured, have created a climate in which human rights violations will flourish unless there is absolute respect for the rule of law, including fundamental principles of human rights and humanitarian law,' the organisation said.

Israeli helicopter gunships fired on targets in Ramallah/al-Bireh and Gaza City earlier today near the Palestinian Authority's headquarters in those towns. There have been reports that civilians have been injured in Ramallah/al-Bireh.

According to media reports the Israel Defence Forces has stated: 'Army helicopters today attacked Palestinian police buildings where two army reservist were lynched, as well as other targets. ... This operation was a symbolic warning to the Palestinian leadership to let it know we will not stand idly by in the face of violence,'

The attacks appeared to be in response to the reported killing of at least two Israeli soldiers in Ramallah/al-Bireh earlier today. The exact circumstances of their deaths remain unclear. A group of soldiers were in the custody of the Palestinian Authority at the Ramallah/al-Bireh police headquarters. A large number of civilians reportedly entered the police station and attacked the soldiers. The Palestinian Authority has stated that it made all efforts to protect the soldiers, but was unable to do so. According to media reports the Israeli government holds the Palestinian Authority responsible for the attacks.

'Today's events confirm the need for the United Nations to establish urgently an independent international investigation to investigate all allegations of serious human rights abuses that have taken place since 29 September in Israel, the Occupied Territories and south Lebanon,' the organisation said.
