President Donald Trump has adopted a significantly more pragmatic approach to negotiations over Iran’s nuclear programme than was the case in his first term.

The Trump administration may abandon its mediation efforts with Russia and Ukraine if the conflict continues unabated without progress toward peace.

“If it is not possible to end the war in Ukraine, we need to move on,” US Secretary of State Marco Rubio told reporters Friday after meeting European and Ukrainian officials for negotiations in Paris. “The President has spent 87 days at the highest level of this government repeatedly taking efforts to bring this war to an end.”

The US will abandon trying to broker a Russia-Ukraine peace deal within days unless there are clear signs a truce can be reached, US Secretary of State Marco Rubio has warned.

"We're not going to continue with this endeavour for weeks and months on end," Rubio said, adding that the US had "other priorities to focus on".

Russia launched a full-scale invasion of Ukraine in 2022 and has placed a number of conditions on any potential ceasefire.

The United States will abandon efforts to end the war in Ukraine if it proves impossible to broker meaningful progress in the next several days, Secretary of State Marco Rubio said as he departed Paris on Friday a day after meeting with President Emmanuel Macron of France.

“If it is not possible to end the war in Ukraine, we need to move on,” Mr. Rubio told reporters, adding that the Trump administration would decide “in a matter of days whether or not this is doable in the next few weeks.”

Iran and the United States have begun talks in Oman over Tehran's nuclear programme - the highest level meeting between the two nations since 2018.

President Trump’s escalating tariff battle with China is rattling the global economy and raising questions about how the standoff will end.  

Trump this week announced a 90-day pause on his sweeping tariffs against dozens of countries, but he bumped up import taxes on China to a staggering 145 percent total. China hit back by upping its own tariffs to 125 percent on Friday, raising the stakes as the hikes roil global markets.  

The Pentagon fired the commander at the U.S. Space Force base in Greenland after she distanced herself from Vice President JD Vance, who recently visited the headquarters. 

After the vice president’s visit, Col. Susannah Meyers emailed base personnel on March 31, writing, "I do not presume to understand current politics, but what I do know is the concerns of the U.S. administration discussed by Vice President Vance on Friday are not reflective of Pituffik Space Base."

Columbia University graduate student Mahmoud Khalil can be kicked out of the U.S. as a national security risk, an immigration judge in Louisiana found Friday during a hearing over the legality of deporting the activist who participated in pro-Palestinian demonstrations.

The government’s contention that Khalil’s presence in the United States posed “potentially serious foreign policy consequences” was enough to satisfy requirements for his deportation, Immigration Judge Jamee E. Comans said at the conclusion of a hearing in Jena.
