Hundreds of thousands pf people are expected to flood downtown London today to demand that the final decision on the Brexit should be made by the public.  It's likely to be one of the largest political protests that the UK has ever seen.  Supporters of the Final Say movement will march from Park Lane to Parliament Square, calling for a fresh public vote on the Brexit deal that Prime Minister Boris Johnson struck with the European Union, and that the ballot contain an option to Remain in the EU.  Johnson insists his deal is the best one; Labour leader Jeremy Corbyn said it was a "worse deal" than the one the previous PM Theresa May struck with Brussels, and his party will vote against it.

Two NASA astronauts replaced a failed power control unit on the International Space Station (ISS), successfully completing the first all-female spacewalk in the history of Earth's space exploration.  Christina Koch had already performed four previous spacewalks; this was the first for Jessica Meir.  The failed battery charge-discharge unit (BCDU) they replaced will later be placed in the next SpaceX Dragon resupply ship and taken back to earth for inspection.

US Senate Republican leader Mitch McConnell says Donald Trump is making a "grave mistake" with his Syrian policy.  In a new op-ed piece in the Washington Post, McConnell said the decision to withdraw troops from Syria "will leave the American people and homeland less safe, embolden our enemies, and weaken important alliances", and predicts more terrorism in "Syria and Afghanistan if we abandon our partners and retreat from these conflicts before they are won".  McConnell's op-ed comes after Vice President Pence announced Thursday that the United States and Turkey had agreed to a five-day cease-fire, during which the United States won't apply additional sanctions on Turkish officials.

At the White House, Trump claimed the cease-fire is holding - But Kurdish officials say Turkey has already violated that cease-fire.  Turkish artillery peppered the border town of Ras al-Ain, which falls within the 30 kilometer "safe zone" that Turkish President Recep Tayyip Erdogan wants to established on the other side of his southern border - territory that the Kurds cleared of Islamic State militants with the help of US air power.  "The situation inside the Ras al-Ain Hospital is catastrophic.  Three ambulance vehicles belonging to the Kurdish Red Crescent were prevented from entering and were shot at.  The city is completely surrounded by air and ground from the Turkish military," said Kurdish spokesman Merivan Qamishlo.
