ANKARA, Jan 12 (Reuters) - Turkey said on Monday that any foreign intervention in neighbouring Iran would lead to greater crises in the country and the region, and it called for U.S. and Iranian negotiations to resolve existing problems.

Iran is facing its biggest demonstrations since 2022 and U.S. President Donald Trump has threatened to get involved if force is used against protesters.

NATO member Turkey does not wish to see chaos in Iran despite "certain problems within Iranian society and government", Omer Celik, spokesperson for Turkey's ruling AK Party, said.

CAIRO, Jan 12 (Reuters) - An Israeli-backed Palestinian militia said on Monday it had killed a senior Hamas police officer in the southern Gaza Strip, an incident which Hamas blamed on "Israeli collaborators".

A statement from the Hamas-run interior ministry said gunmen opened fire from a passing car, killing Mahmoud Al-Astal, head of the criminal police unit in Khan Younis, in the south of the enclave. It described the attackers as "collaborators with the occupation".

US President Donald Trump announced a 25 percent tariff on any country doing business with Iran, ramping up pressure as a rights group estimated a crackdown on protests has killed at least 648 people.

Trump, who has repeatedly threatened Iran with military intervention, said in a social media post on Monday that the new levies would "immediately" hit the Islamic republic's trading partners who also do business with the United States.

"This Order is final and conclusive," he wrote, without specifying who they will affect.

Barham Salih has known torture and the wrenching loss of exile. Four decades after his own ordeal, he has taken the helm of the UN refugee agency as it grapples with a funding shortfall and ever-rising needs.

A former Iraqi president, Salih, 65, became the first former head of state to run the United Nations High Commission for Refugees (UNHCR) at the start of the year.

"It is a profound moral and legal responsibility," Salih told AFP during his first trip in the new role -- to Kakuma refugee camp in Kenya.

WASHINGTON, D.C., Jan 11 (Reuters) - U.S. President Donald Trump said on Sunday that he plans to speak with billionaire entrepreneur Elon Musk about restoring internet in Iran, where authorities blacked out service amid ongoing anti-government protests.

"He's very good at that kind of thing, he's got a very good company," Trump told reporters in response to a question about whether he would engage with Musk's SpaceX company, which offers a satellite internet service called Starlink that has been used in Iran.
