Thousands of people have attended the funeral of a 15-year-old Palestinian boy.

Mohammed Dudin was killed in the occupied West Bank during an arrest raid by Israel Defence Forces (IDF) looking for three Israeli teenagers who went missing over a week ago.

IDF said troops had fired live ammunition when rocks and firebombs were thrown at them during the raid.

Dodeen was one of two Palestinians killed by Israeli soldiers in clashes during West Bank raids on Friday.

His death brings the number of Palestinians shot dead by IDF troops since the search operation began to three, according to figures released by Associated Press.

Israel accuses Hamas of taking the three teenagers but has offered no proof.

Hamas has not issued any denial of involvement.

During a Hamas demonstration on Friday, protesters staged a mock kidnapping.

Palestinian President Mahmoud Abbas has condemned the abductions but asserted that the extend of Israel’s raids amounted to collective punishment and urged they be condemned.

United Nations Middle East envoy Robert Serry urged all sides to show restraint and bring about the “immediate release of the kidnapped Israelis.”

“We call for restraint and expect Israel to carry out the related security operation in compliance with international law and respect for the lives, dignity and livelihoods of Palestinians,” Serry said in a written statement to reporters.

Meanwhile, there is still no sign of the three missing students. IDF troops continue their search near where the abductions are believed to have taken place.

Israeli Prime Minister Benjamin Netanyahu met with the parents of the missing teenagers. During the two-hour meeting he assured them a tremendous effort has been invested to bring the boys home.
