INTERNATIONAL: U.S. President Joe Biden has arrived in Brussels on Wednesday,March 23, ahead of emergency NATO, G7 and EU summits to discuss the ongoing Russian invasion of Ukraine.

Biden's trip includes talks in Brussels with NATO and European leaders and a visit to Warsaw for consultations with Polish President Andrzej Duda.

On Thursday ,March 24, Biden will attend an emergency NATO summit, meet with G7 leaders and address the 27 leaders of the European Union at a session of the European Council.

Speaking to reporters on the Air Force One flight to Brussels, White House national security adviser Jake Sullivan has said Biden will announce a package of Russia-related sanctions on political figures and oligarchs after the meeting.

Western leaders have grown increasingly concerned that Russian President Vladimir Putin will use chemical weapons or otherwise escalate tactics four weeks into an invasion where his troops have failed to capture a single major Ukrainian city.

Biden has vowed not to engage in direct conflict with Russia but has pledged the United States will defend all NATO territory. He has ordered more U.S. troops to NATO's eastern flank to reassure edgy allies.

During his visit to Poland, a NATO member, Biden will visit U.S. troops and meet with experts involved in the humanitarian response to helping hundreds of thousands of Ukrainians who have fled their country and those who remain.
