EU foreign affairs chief Josep Borrell said the package approved Tuesday "will hurt Russia, and it will hurt a lot."

Libya's embattled prime minister is warning that the appointment of a new interim government could set off war and chaos in a Mediterranean country mired for a decade in turmoil.

Addressing Libyans late Monday, Prime Minister Abdul Hamid Dbeibah reiterated his insistence that he will hand over power only to an elected government. He mapped out a likely unrealistic plan to hold elections in June.

Oil prices surged nearly 5% and stock prices dropped after Russian President Vladimir Putin ordered forces into separatist regions of eastern Ukraine, bringing a long-feared invasion a step closer.

Former Prime Minister Saad Hariri's estranged older brother, Bahaa, says he hopes upcoming elections in crisis-hit Lebanon will bring about a new generation of leaders, adding that he'll do whatever he can to bring about positive change and accountability for past corruption.

Bahaa Hariri also describes Lebanon's Iran-backed Hizbullah as a "terrorist" organization, calling it part of the country's "failed past."

Russian President President Vladimir Putin on Monda recognized the independence of separatist regions in eastern Ukraine — a move that will severely ratchet up tensions with the West amid fears that his country could invade Ukraine at any moment and use skirmishes as a pretext for an attack.

Putin's announcement comes after a meeting of the presidential Security Council and paves the way for Russia to openly send troops and weapons to the long-running conflict pitting Ukrainian forces against Moscow-backed rebels.

The U.S. Navy's Mideast-based 5th Fleet announced Monday the launch of a new joint fleet of unmanned drones with allied nations to patrol vast swaths of the region's volatile waters as tensions simmer with Iran.

Vice Adm. Brad Cooper, who leads the 5th Fleet, told The Associated Press that 100 unmanned drones, both sailing and submersible, would dramatically multiply the surveillance capacities of the U.S. Navy, allowing it to keep a close eye on waters critical to the flow of the global oil and shipping. Trade at sea has been targeted in recent years as Tehran's nuclear deal with world powers collapsed.

Russia's military buildup along its border with Ukraine is testing the possibility of a Moscow-Beijing axis lining up against the U.S. and its allies.

World leaders are making another diplomatic push in hopes of preventing a Russian invasion of Ukraine, even as heavy shelling continues in Ukraine's east and the Kremlin considered recognizing the independence of the separatist regions in eastern Ukraine.

The White House said President Joe Biden had agreed "in principle" to meeting with Russian President Vladimir Putin if he refrains from launching an assault on his neighbor that U.S. officials say appears increasingly likely.

Israel on Monday said it successfully tested a new naval air defense system, intercepting a series of threats in what officials called a key layer of protection against Iran and its proxies in the region.

The "C-Dome" system is a naval version of the Iron Dome, which has been used to shoot down rockets fired from the Gaza Strip for the past decade. The C-Dome is being installed on Israel's latest-generation corvette warships, which protect Israel's coastline and offshore natural gas assets in the Mediterranean.

Israel's prime minister has criticized an emerging deal over Iran's nuclear program, saying it would be weaker than a previous agreement and would create a "more violent, more volatile Middle East."

World powers have been negotiating in Vienna in a bid to revive the 2015 nuclear deal, which was left in tatters after the Trump administration, goaded by Israel, withdrew.
