For a year, Donald Trump has governed the United States with little standing in his way.

Israeli strikes on the country's east and south killed at least twelve people on Friday, with Israel's army saying it targeted militant group Hezbollah and its Palestinian ally Hamas.

A Hezbollah source told AFP that a military leader from the Iran-backed group was among the dead in the strikes in the eastern Bekaa Valley.

Hamas condemned Friday an Israeli strike on the country's largest Palestinian refugee camp that killed two people.

In a statement, Hamas said the attack led to "civilian" casualties.

Britain's former prince Andrew was arrested and released under investigation in a day of drama. What is he being probed for? Could he be jailed? And what next?

President Donald Trump warned on Friday that limited strikes against Iran are possible even as the country's top diplomat said Tehran expects to have a proposed deal ready in the next few days following nuclear talks with the United States.

In response to a reporter's question on whether the U.S. could take limited military action as the countries negotiate, Trump said, "I guess I can say I am considering that." A few hours later, he told reporters that Iran "better negotiate a fair deal."

An Israeli strike on Lebanon's largest Palestinian refugee camp killed two people on Friday, with Israel's army saying it had targeted the Palestinian militant group Hamas.

Iran has warned that U.S. bases, facilities and assets would be "legitimate targets" if the United States follows through on its military threats and attacks.
