Gaza, Al Ray - The United Nation's Special Envoy to the Middle East, Robert Serry, lashed out at the killing of Palestinian boy Mohammed Abu Khudair in East Jerusalem neighborhood of Shuafat. 

Serry Wednesday said in a statement that "I strongly condemn the murder of the Palestinian child that took place in Jerusalem," urging to bring the perpetrators to justice. 

He added: "I am reiterating the UN Secretary-General’s message that any deliberate killing of civilians is no justified. All parties should take the necessary measures to avoid any escalation, and we are all sympathetic with the bereaved family."

A Palestinian teenager from occupied East Jerusalem was kidnapped and killed early Wednesday in a suspected act of revenge for the killing of three Israeli youths, Israeli army radio reported.
