An official with the committee preparing a national dialogue conference in Syria to help chart the country's future said Friday that it has not been decided whether the conference will take place before or after a new government is formed.

The date of the conference has not been set and the timing "is up for discussion by the citizens," Hassan al-Daghim, spokesperson for the committee, told The Associated Press in an interview in Damascus Friday.

Hamas's armed wing confirmed it will hand over Saturday six hostages held alive in the Gaza Strip as part of the ongoing ceasefire deal with Israel.

The Ezzedine al-Qassam Brigades said in a statement on Friday that the release would occur as planned. Israeli campaign group the Hostages and Missing Families Forum published the names of the six hostages earlier this week, naming them as Eliya Cohen, Tal Shoham, Omer Shem Tov, Omer Wenkert, Hisham Al-Sayed and Avera Mengistu.

Israeli Prime Minister Benjamin Netanyahu on Friday ordered an "intensive operation against centers of terrorism" in the occupied West Bank, his office said, after three buses exploded in central Israel without causing any reported injuries.

Arab leaders were gathering in Saudi Arabia on Friday to hammer out a recovery plan for Gaza aimed at countering President Donald Trump's proposal for U.S. control of the territory and the expulsion of its people.

Israeli Prime Minister Benjamin Netanyahu says a body that Hamas militants released during the handover of remains of Israeli hostages is that of a woman from Gaza instead of that of Shiri Bibas, the mother of two young boys whose bodies were returned on Thursday.

In a statement released Friday, Netanyahu criticized the handover of the wrong remains as a "cruel and malicious violation" of the ceasefire agreement, which has halted fighting in the Gaza Strip, and said Hamas would "pay the full price" for the action.

Israeli police said that explosions rocked several buses in the central city of Bat Yam on Thursday evening in what they described as a "suspected terror attack", with an official saying that there were no injuries.

Israeli Prime Minister Benjamin Netanyahu said Israel was "enraged by the monsters of Hamas" Thursday and vowed to "eliminate" the Palestinian militants after they paraded the coffins of four Israeli hostages in Gaza.

"We are all enraged at the monsters of Hamas," he said in a video statement, adding: "We will return all our hostages, destroy the murderers, eliminate Hamas and together -- with God's help -- we will secure our future."

The new United Nations envoy to Libya pledged on Thursday to "spare no effort in achieving peace and stability" in the divided country, said the U.N. Support Mission in Libya.

At least seven civilians, including a woman and a child, were killed on Thursday when unexploded munitions ignited at a house in northwestern Syria, a war monitor said.

The Syrian Observatory for Human Rights reported the deadly blast a day after another organization said two-thirds of Syrians risked being killed or wounded by unexploded ordnance.

Hamas released the bodies of four Israeli hostages, said to include a mother and her two young children, in the first time the remains of hostages have been released since a fragile ceasefire began in January.

The remains sent to Israel on Thursday were said to be of Shiri Bibas and her two children, Ariel and Kfir, as well as Oded Lifshitz, who was 83 when he was abducted. Kfir, who was 9 months old when he was taken, was the youngest captive. Hamas has said all four were killed along with their guards in Israeli airstrikes.
