Israeli Prime Minister Benjamin Netanyahu said Sunday the corruption cases against him were tearing Israel apart, after he submitted a formal request for a pardon in the long-running trials.

A new draft law on conscripting ultra-Orthodox Jews, whose support is crucial for Prime Minister Benjamin Netanyahu's government, has sparked uproar in Israel, with the opposition denouncing it as a special privilege for "draft-dodgers".

Syria on Friday condemned an Israeli military operation in southern Syria that killed 13 people overnight as a "war crime".

"Syria denounces... the criminal aggression" of the Israeli army in the village of Beit Jin, the foreign ministry said in a statement, adding that such acts aim to "ignite the region" in conflict.

Israeli forces on Thursday killed a pair of Palestinian men in the occupied West Bank after they appeared to surrender to troops, drawing Palestinian accusations that the men were executed "in cold blood." The Israeli military said it was investigating.

The killings, captured in videos shown on two Arab TV stations, came as Israel pressed ahead with its latest offensive in the West Bank, where the army has stepped up its activities over the past two years. Israel says it is cracking down on militants, but Palestinians and rights groups accuse Israel of using excessive force and say dozens of unarmed civilians have been killed.

Dozens of Tunisian political figures were sentenced on appeal to up to 45 years in prison for plotting against the state, local media reported Friday, in a trial rights groups have condemned as politically motivated.

"The Court of Appeal in Tunis issued a final ruling early Friday against the defendants in what is known as the conspiracy against the state case," said radio station Mosaique FM, citing an official source, adding the terms ranged from five to 45 years.

Israeli forces killed 13 people on Friday in an operation in southern Syria, saying they targeted an Islamist group, in Israel's deadliest attack on the country since Bashar al-Assad's overthrow last year.

Iraq said on Thursday it would investigate an attack on an Emirati-owned gas complex in the autonomous Kurdistan region, which disrupted gas supplies and caused power cuts.

Sabah al-Numan, the military spokesman for the Iraqi prime minister, said in a statement that the caretaker PM Mohammed Shia al-Sudani had ordered "the formation of a high-level investigative committee" to look into the attack.

The appeal trial of dozens of Tunisian public and opposition figures, jailed on charges of plotting against the state, resumed on Thursday, said an AFP journalist in the courtroom.

Nearly 40 defendants were sentenced to prison in April on charges of "conspiracy against state security" and "belonging to a terrorist group".

The Palestinian militant group Hamas called on mediating countries Wednesday to pressure Israel to allow safe passage for dozens of its fighters holed up in tunnels in the southern Gaza Strip.

The request came after the Israeli military said it killed over 20 Hamas members over the past week "who attempted to flee from the underground terror infrastructure in the area", and apprehended eight more.

Children and families in Gaza scooped muddy water from their tents on Tuesday, trying to protect the few belongings that remain after two years of war.

Winter's heavy rains have left displaced Palestinians splashing in water that reaches their ankles, and blaming both Israel and Hamas for the misery that remains despite a ceasefire.
