Iran's atomic energy chief Mohammad Eslami said Thursday that no country can deprive the Islamic republic of its right to nuclear enrichment, after U.S. President Donald Trump again hinted at military action following talks in Geneva.

"The basis of the nuclear industry is enrichment. Whatever you want to do in the nuclear process, you need nuclear fuel," said Eslami, according to a video published by Etemad daily.

Israel's increased attacks and forcible transfers of Palestinian civilians "raise concerns over ethnic cleansing" in the Gaza Strip and the West Bank, the United Nations said Thursday.

"Intensified attacks, the methodical destruction of entire neighborhoods and the denial of humanitarian assistance appeared to aim at a permanent demographic shift in Gaza", the U.N. human rights office said in a report.

The United States will deter Iran from acquiring nuclear weapons "one way or the other", U.S. Energy Secretary Chris Wright warned on Wednesday.

"They've been very clear about what they would do with nuclear weapons. It's entirely unacceptable," Wright told reporters in Paris on the sidelines of meetings of the International Energy Agency.

France's hard-left France Unbowed party said Wednesday it had to evacuate its Paris headquarters following a "bomb threat", after it was accused of partial responsibility in the killing of a far-right activist.

"The national headquarters of LFI have just been evacuated following a bomb threat. Police services are on site. All employees and activists are safe," the party's coordinator Manuel Bompard said on X.

The U.N. missions for 85 member states issued a joint statement Tuesday condemning Israel's encroaching control of the West Bank, which critics say amounts to de facto annexation of the Palestinian territory.

"We strongly condemn unilateral Israeli decisions and measures aimed at expanding Israel's unlawful presence in the West Bank," the statement reads. "Such decisions are contrary to Israel's obligations under international law and must be immediately reversed."

What began as an ordinary shift for Jerusalem bus driver Fakhri Khatib ended hours later in tragedy.

A chaotic spiral of events, symptomatic of a surge in racist violence targeting Arab bus drivers in Israel, led to the death of a teenager, Khatib's arrest and calls for him to be charged with aggravated murder.

Iran and Russia will conduct naval maneuvers in the Sea of Oman on Thursday, following the latest round of talks between Tehran and Washington in Geneva, Iranian media reported.

On Monday, the Revolutionary Guards, the ideological arm of Iran's military, also launched exercises in the strategic Strait of Hormuz, a challenge to U.S. naval forces deployed in the region.

Ukraine and Russia did not find agreement on the central issues of how to end the four-year at U.S.-mediated talks in Geneva, Ukrainian President Volodymyr Zelensky said Wednesday.

"We can see that some groundwork has been done, but for now the positions differ, because the negotiations were not easy," Zelensky said in a message to journalists, including from AFP, after the talks had finished.

The Israeli military announced that one of its soldiers had been killed in combat in southern Gaza on Wednesday, but a security source said the death appeared to have been caused by "friendly fire".

"Staff Sergeant Ofri Yafe, aged 21, from HaYogev, a soldier in the Paratroopers Reconnaissance Unit, fell during combat in the southern Gaza Strip," the military said in a statement.

School bus driver Ali al-Dorr averts his gaze every time he passes the rubble of his son's home -- destroyed by an Israeli strike in south Lebanon despite a year-old ceasefire.

Though his son managed to evacuate in time, the attack left notebooks, papers and furniture strewn among the debris of the apartment building in Qannarit, overlooking the coastal city of Sidon, the scene of several strikes in recent weeks that Israel says targeted Hezbollah.
