Barcelona and its surrounding in northeastern Spain's Catalonia region are preparing for tighter water restrictions amid a historic drought that has shrunk reservoirs to record lows.

Catalan authorities are expected to declare a drought emergency Thursday for an area that is home to 6 million people after water reserves fell below 16% of their capacity, the benchmark set for the application of a new round of water-saving measures.

European Union leaders at a summit on Thursday will focus on the one member state blocking a 50-billion-euro ($54 billion) war support package for Ukraine: Hungary, the country in the bloc with the closest ties to Russia.

Almost two years after Russian President Vladimir Putin launched the invasion of Ukraine, the war has ground to a virtual stalemate and Ukraine desperately needs financial assistance.

The European Union plans to launch a naval mission in the Red Sea within three weeks to help defend cargo ships against attacks by Houthi rebels in Yemen that are hampering trade and driving up prices, the bloc's top diplomat said Wednesday.

EU foreign policy chief Josep Borrell said he wants the mission to be up and running by Feb. 17. Officials say that seven EU countries are ready to provide ships or planes. Belgium has already committed to send a frigate. Germany is expected to do the same.

Farmers blocked more traffic arteries across Belgium, France and Italy on Wednesday, as they sought to disrupt trade at major ports and other economic lifelines. They also moved closer to Brussels on the eve of a major European Union summit, in a continued push for better prices for their produce and less bureaucracy in their work.

The protests had an immediate impact on Wednesday, as the EU's executive commission announced plans to shield farmers from cheap exports from wartime Ukraine and allow farmers to use some land that had been forced to lie fallow for environmental reasons.

Former Pakistani Prime Minister Imran Khan was found guilty of corruption on Wednesday and sentenced to 14 years, yet another blow to the imprisoned populist leader days before his political movement attempts a return to power in parliamentary elections.

It was his second conviction in as many days and the harshest yet, and was the latest episode in the long-running battle between the powerful military and civilian leaders in the troubled Western ally.

The doors close Wednesday on nominations for the 2024 Nobel Peace Prize, with peace activists connected to the wars in Gaza and Ukraine among the known entries.

The Norwegian Nobel Committee keeps the nominations secret, but those with nomination rights sometimes make their picks public.

Iran threatened Wednesday to "decisively respond" to any U.S. attack on the Islamic Republic following President Joe Biden's linking of Tehran to the killing of three U.S. soldiers at a military base in Jordan.

The U.S. has signaled it is preparing for retaliatory strikes in the Mideast in the wake of the Sunday drone attack that also injured at least 40 troops at Tower 22, a secretive base in northeastern Jordan that's been crucial to the American presence in neighboring Syria.

President Joe Biden has made it clear the U.S. will strike back after a deadly drone attack killed three service members and wounded more than 40 at a small base in Jordan over the weekend. What isn't yet clear is who will be hit, where, and how hard.

Biden has a wide array of options, but the U.S. must walk a fine line: A weak response will do little to deter further attacks by Iran-backed militia groups, while a major assault risks expanding the turmoil in the Middle East and drawing America into a wider conflict.

President Joe Biden has indicated he had decided how to respond after the killing of three American service members Sunday in a drone attack in Jordan that his administration has pinned on Iran-backed militia groups, saying he does not want to expand the war in the Middle East but demurring on specifics.

U.S. officials said they are still determining which of several Iran-backed groups was responsible for the first killing of American troops in a wave of attacks against U.S. forces in the region since the Oct. 7 Hamas assault on Israel. Biden plans to attend the dignified transfer to mark the fallen troops' return to American soil on Friday and answered in the affirmative when asked by reporters if he'd decided on a response, as he indicated he was aiming to prevent further escalation.

The first United Arab Emirates ambassador to Damascus in nearly 13 years has taken up his post as Syria has been reintegrating into mainstream regional acceptance.

Syrian state media said Tuesday the country's Foreign Minister Faisal Mekdad received Ambassador Hassan Ahmad al-Shihi's credentials.
