The United States said Thursday that a new response from Iran on reviving a landmark nuclear deal was "not constructive," a day after European mediators were hopeful at finally crossing the finish line.

It is the latest in a back and forth between the adversaries via the European Union, which in August broke a deadlock after a year and a half of slow-moving diplomacy.

The European Union put forward on August 8 what it called a final text to restore the 2015 nuclear accord, which was trashed by former US president Donald Trump.

Yemeni rebel fighters paraded through Hodeida Thursday drawing a stern reminder from the United Nations to abide by a hard-won 2018 agreement to demilitarise the Red Sea port city.

The rebels' Al-Masirah television channel aired footage of the parade it said involved air and naval forces as well as hundreds of uniformed troops.

The parade drew a rebuke from the UN mission deployed to oversee the deal the rebels reached with the government and its Saudi-led supporters in Sweden four years ago to avert potentially devastating fighting for the city's lifeline port.

Israel's President Isaac Herzog is to attend a memorial next week for 11 Israelis killed in an attack at the 1972 Olympic Games in Munich, his office said Thursday.

Herzog's participation alongside his German counterpart Frank-Walter Steinmeier follows Berlin striking a compensation deal with relatives of the Israeli victims.

"The memorial will be attended by a large audience, including the victims' families, representatives of the Olympic Committee of Israel, and leaders of Germany," Herzog's office said in a statement.

Even as he battles Lebanon's summer heat without air-conditioning, judge Faysal Makki tries not to drink too much water because the toilets at the Justice Palace are broken.

His printer still works, but if he wants to use it he needs to bring his own paper and ink cartridges because the ministry can no longer afford office supplies.

State institutions have reached a state of disrepair that mirrors Lebanon's broader unravelling amid a political crisis and economic turmoil branded by the World Bank as one of the worst globally in modern times.

Four militants were killed overnight after an ambush in the southern Iraqi city of Basra sparked clashes between rival Shiite factions, a security source said Thursday, days after deadly clashes in the capital.

Two members of Saraya al-Salam -- an armed faction linked to powerful Shiite cleric Moqtada Sadr -- were killed when their vehicle came under fire from the Asaib Ahl al-Haq force, which lost two fighters in the ensuing gun battle, the source said.

Two Palestinians were killed by Palestinian fire during separate clashes with the Israeli army in the occupied West Bank early Thursday, Palestinian sources said.

The Palestinian health ministry said that Samer Khaled, 25, from Al-Ain camp in Nablus, was killed by a gunshot to the neck, while Yazan Afana, 26, from Qalandia camp outside Jerusalem, died from a shot to the heart.

The Palestinians' official Wafa news agency said Khaled was killed during an Israeli army raid on Balata refugee camp outside Nablus.

Veteran rights campaigner Shawan Jabarin peers down the street from his office in the occupied West Bank as if awaiting the imminent arrival of Israeli forces after a crackdown on NGOs.

"I dislike going to jail, but if this is the price to defend human rights and to keep speaking out in the face of the oppressive regime, I'm ready for that," said 62-year-old Jabarin, doyen of the small world of Palestinian non-governmental organisations.

Volodymyr is celebrating a major milestone on Wednesday -- it's his final day of taking a new treatment hailed as a turning point in the fight against drug-resistant tuberculosis.

The 25-year-old doctor in Ukraine's capital Kyiv said he had nasty neurological side effects when he was on a previous drug regimen, which takes up to two years, involves a huge number of pills and is less than 60-percent effective.

But the new treatment course took just six months, and gave him very few side effects. "It was very easy," he told AFP.

A Palestinian prisoner held by Israel said Wednesday an agreement had been reached to release him and that he was therefore ending a hunger strike he began five months ago.

Khalil Awawdeh, a militant from the southern West Bank, has been held without charge by Israel since December and had been refusing food since March, apart from a respite of a few days.

The 40-year-old, held in custody in an Israeli hospital, was said to be in critical condition and his life in danger.

The EU's foreign policy chief voiced hope Wednesday at reviving the Iran nuclear deal within days as Israel's leader, a strong opponent, made his case with US President Joe Biden.

The Biden administration is eager to restore the deal trashed by former president Donald Trump and says that Iran has backed down on some demands that held up diplomacy for a year and a half.

"I am hoping that in the coming days we are not going to lose this momentum and we can close the deal," top EU diplomat Josep Borrell said after an informal meeting of the bloc's foreign ministers in Prague.
