Feb 6 (Reuters) - The United States and Iran on Friday were trying to reach a diplomatic solution to disputes between the two nations that have led to heightened tensions in the Middle East, and warnings from President Donald Trump that military options are at his disposal.

While Washington wants talks to include the nuclear program, ballistic missiles, support for armed groups and treatment of the Iranian people, Tehran has insisted on focusing exclusively on its disputed nuclear program and is seeking recognition of its right to enrich uranium.

Thousands turned out on Friday for the burial of the slain son of former Libyan ruler Muammar Gaddafi in a town that still holds allegiance to the late longtime leader.

Seif al-Islam Gaddafi, once seen by some as Libya's heir apparent, was shot dead in his home in the northwestern city of Zintan on Tuesday.

His burial in the town of Bani Walid, some 175 kilometres (110 miles) south of Tripoli, brought together thousands of Gaddafi loyalists, nearly 15 years after the ruler was toppled and killed in a 2011 NATO-backed uprising.

Some came from other parts of the country.

One of the "key participants" behind the 2012 attack on the US mission in Benghazi that left the ambassador and three other Americans dead has been arrested, officials said Friday.

Attorney General Pam Bondi said the suspect, Zubayr al-Bakoush, has been brought to the United States and will face murder and other charges.

"The FBI has arrested one of the key participants behind the Benghazi attack," Bondi said at a press conference. "Bakoush will now face American justice on American soil."

WASHINGTON, Feb 6 (Reuters) - The United States has arrested a person suspected of playing a role in the 2012 attack on the U.S. consulate in Benghazi, Libya. Attorney General Pam Bondi said on Friday.

Bondi said Zubayar al-Bakoush has been extradited to the United States and will face murder, arson and terrorism related charges.

French Foreign Minister Jean-Noel Barrot said Friday that Lebanon's army must be given the means to disarm militant group Hezbollah and replace a United Nations peacekeeping force after its mandate ends this year.

On the final stop of a regional tour that has taken him to Syria and Iraq, Barrot was meeting senior officials in Beirut on Friday, with discussions expected to address preparations for a March conference in Paris in support of the Lebanese army.

"France's vision for Lebanon is that of a strong, sovereign state holding a monopoly on arms," Barrot told AFP.

GAZA/CAIRO, Feb 6 (Reuters) - Eatedal Rayyan waited for this moment for nearly two years: a reunion with her husband in Gaza, where she says yearning for family and homeland has persisted despite widespread destruction from the enclave's two-year war.

Rayyan, 29, left Gaza with her mother and three children after suffering a leg injury that doctors warned could need amputation if left untreated. She was one of tens of thousands who fled to Egypt in the early months of the conflict.

PARIS, Feb 6 (Reuters) - France and Bahrain have signed a bilateral deal on defence which includes strategic information sharing, the office of French President Emmanuel Macron said on Friday.

OSLO, Feb 6 (Reuters) - Norway looks set to launch an inquiry into its own foreign ministry over links to late U.S. sex offender Jeffrey Epstein, one of several European nations to feel the heat from a scandal that has yet to cause major political repercussions in the U.S.

The release of an enormous cache of new files last week has revealed a host of new Epstein connections with politicians, royals and the ultra-rich.

STOCKHOLM, Feb 6 (Reuters) - Sweden's centre-right government said on Friday it planned to make all asylum seekers live in migrant reception centres while their cases are processed, in a further tightening of immigration regulations.

People will have to prove that they have moved to the centres, or risk losing their benefits, and also agree to travel restrictions, Migration Minister Johan Forssell told reporters.
