Syrian government forces were advancing towards the southern city of Sweida on Monday to quell deadly clashes between Druze fighters and Bedouin tribes, with one Druze armed group saying talks with authorities aimed at brokering a truce were underway.

The Syrian Observatory for Human Rights war monitor reported 99 people killed since the fighting erupted on Sunday -- 60 Druze, including four civilians, 18 Bedouin fighters, 14 security personnel and seven unidentified people in military uniforms.

After years in a Syrian detention camp, Ibrahim Darwish was relieved to be allowed to return home to Iraq, but his joy was quickly punctured by the harsh reality that he had to disown his sons accused of being jihadists.

"All I wanted was to return to Iraq," the 64-year-old said of his time in the Kurdish-controlled al-Hol camp, where family members of suspected Islamic State group fighters are held in prison-like conditions alongside refugees and displaced people.

But back home in Iraq, "I had to disown my sons. My house is gone," he said. "I am back to square one."

Palestinian-American Saif al-Din Abdul Karim Musalat's body -- draped in a flag and covered with a yellow and orange wreath -- was carried through the crowded streets of Al-Mazra'ah ash-Sharqiyah in the occupied West Bank on Sunday.

The village, perched atop limestone hills, is known for its colonnaded villas and manicured gardens -- and its few thousand residents who mostly come from the Palestinian diaspora in North America.

Gaza's civil defence agency said Israeli air strikes on Sunday killed more than 40 Palestinians, including children at a water distribution point, as talks for a ceasefire between Israel and Hamas stalled.

Delegations from Israel and the Palestinian militant group have now spent a week trying to agree on a temporary truce to halt 21 months of devastating fighting in the Gaza Strip.

On the ground, civil defence agency spokesman Mahmud Bassal said eight children were among the 10 victims of a drone strike at a water point.

Southeast Turkey, where the army has battled Kurdish militants for decades, is not yet convinced that lasting peace is at hand.

In a slickly managed ceremony across the border in Iraq Friday, members of the Kurdish rebel group PKK destroyed their weapons as part of a peace process underway with the Turkish state.

But on the streets and in the tea houses of Hakkari, a Kurdish-majority town some 50 kilometres (31 miles) from the Iraqi border, few people express much hope that the deadly conflict is over.

Iran said Saturday its cooperation with the International Atomic Energy Agency "will take on a new form", expressing a desire for a diplomatic solution to resolve concerns over its nuclear programme.

Iran's 12-day war with Israel last month, sparked by an Israeli bombing campaign that hit military and nuclear sites as well as residential areas, rattled its already shaky relationship with the UN nuclear watchdog.

The attacks began days before a planned meeting between Tehran and Washington aimed at reviving nuclear negotiations, which have since stalled.

Police in several British cities on Saturday arrested scores of people for supporting Palestine Action, following a second consecutive weekend of protests over the government's decision to ban the activist group using anti-terror laws.

Campaign group Defend Our Juries, which had announced the rallies "to defy" the ban, said 86 people had been arrested across five different cities.

Gaza ceasefire talks hung in the balance as Hamas and Israel on Saturday accused the other of blocking attempts to strike a deal, nearly a week into an attempt to halt 21 months of bitter fighting in the Palestinian territory.

A Palestinian source with knowledge of the indirect talks in Qatar told AFP that Israel's proposals to keep its troops in the war-torn territory were holding up a deal for a 60-day pause.

Ten Palestinians were reported killed Friday while waiting for rations in Gaza, adding to nearly 800 similar deaths in the last six weeks, according to the UN, with Israel's army saying it issued new instructions to troops following repeated reports of fatalities.

Friday's reported violence came as negotiators from Israel and the Palestinian militant group Hamas were locked in indirect talks in Qatar to try to agree on a temporary ceasefire in the more than 21-month conflict.

Kurdish militants want to return to Turkey and enter mainstream politics, one of the PKK's joint leaders told AFP on Friday after the group's fighters began destroying their arms at a ceremony in Iraq.

Speaking to AFP after handing in her own weapon alongside 29 of her comrades, the Kurdistan Workers' Party's top female commander Bese Hozat said if Turkey were willing, the disarmament process could be completed very quickly.
