One person was killed and eight wounded in an overnight explosion at an Iraqi military base housing a coalition of pro-Iranian armed groups, officials said Saturday.

The full details remain unclear hours after the blast hit the Kalsu military base in Babylon province south of Baghdad, where regular army, police and members of Iraq's Popular Mobilisation Forces, or Hashed al-Shaabi, are stationed.

It comes days after Iran launched an unprecedented assault on Israel which reportedly responded with a drone strike on the Islamic republic, amid tensions fuelled by the Gaza war.

After years of high-level US pressure on its ally to show restraint, Israel's purported attack on Iran takes the region and Western-led diplomacy into uncharted territory.

Iran and Israel have long waged a shadow war, marked by assassinations of Tehran's nuclear scientists and attacks on Israel by the clerical state's allies in the Arab world such as Lebanon's Hezbollah, but the United States has put a top priority on preventing a wide-scale war.

Palestinian officials said Friday Israeli troops killed a teenager and an adult in the occupied West Bank, while the Israeli army said it killed a "number of terrorists" in a raid.

Since early last year violence has flared across the West Bank, which Israel has occupied since 1967. It has further escalated since Israel's war with Hamas broke out on October 7.

Qais Fathi Nasrallah, 16, was killed by Israeli troops in Tulkarem refugee camp in the northern West Bank, the Palestinian health ministry in Ramallah said.

An international humanitarian relief effort in the form of a Freedom Flotilla Coalition was getting ready Friday to leave the western Turkish port of Tuzla and bring much-needed relief to residents of war-torn Gaza.

At least three vessels carrying some 5,000 tons of food, drinking water and medical aid were awaiting the green light from Turkish authorities to set sail from the port on the Sea of Marmara, south of Istanbul, organisers said.

French authorities Friday detained a man suspected of entering the Iranian consulate in Paris and falsely claiming to be armed with an explosive vest, police and prosecutors said.

No explosives or arms were found on the man or the premises after he surrendered to police following the incident.

The man, born in 1963 in Iran, had already been convicted for setting fire to tyres in front of the entrance of the Iranian embassy in Paris in 2023, the Paris prosecutor's office said.

When record downpours sent water flooding into his Dubai home, Riaz Haq expected the levels to drop once it stopped raining. But instead of falling, the water kept rising higher.

"We went to bed, the water was half-a-metre (half-a-yard)," the British lawyer said, recalling Tuesday's tempest that flooded homes, malls, offices and roads.

"We woke up and it was one metre. My cars were submerged, water to our waist. Everything is ruined."

Despite Friday's announcement of explosions in central Iran, many people appeared unfazed and planned rallies in the capital supporting last weekend's unprecedented Iranian attack on Israel still went ahead.

"We're going to the park to play board games. Everything is just like before," Bahar, 24, an instructor who works with children, told AFP from Isfahan province where the early morning blasts were heard.

"It's just like a normal Friday morning," added Bahar, who said she only heard about the explosions from a friend living abroad.

He might be 80 but Sebastiao Salgado, the Brazilian photojournalist who has spent five decades chronicling the world around us, is not ready to hang up his camera yet.

Salgado, known in particular for his work in the Amazon, insists there is still a need to "raise awareness" about the deforestation of the planet.

"Photography is the mirror on society," he said in an interview with AFP to mark the start of a London retrospective of his 50-year-career.

Gazans in the besieged southern city of Rafah told AFP they believed Israel's reported strike against Iran on Friday was little more than a show -- and called for peace in the region.

"As everybody knows, this is all staged and agreed upon in advance from both sides," resident Alaa Abu Taha said.

"If someone wants to strike, they don't give prior warning or threaten before."

Iran's state media reported explosions in the central province of Isfahan as US media quoted American officials saying Israel had carried out retaliatory strikes on its arch-rival.

French authorities Friday detained a man suspected of entering the Iranian consulate in Paris and claiming to be carrying explosives, police and prosecutors said.

No explosives or arms were found on the man or the premises after he surrendered to police after the incident.

Police arrested the suspect, born in 1963 in Iran, when he exited of his own accord after appearing to have "threatened violent action" inside, the Paris prosecutor's office said.

But "no explosive materials have been observed at this stage," either on him, in his car or in the building, it said.
