#uk: *TENS OF THOUSANDS OF PRO-PALESTINIAN PROTESTERS MARCH IN LONDON* Tens of thousands of pro-Palestinian protesters marched in London on Saturday calling for an end to the war in Gaza, amid concerns that the Iran-Israel conflict could spark wider regional devastation. Protesters waved Palestinian flags, donned keffiyeh scarves and carried signs including "Stop arming Israel" and "No war on Iran" as they marched in the sweltering heat in central London. "It's important to remember that people are suffering in Gaza. I fear all the focus will be on Iran now," said 34-year-old Harry Baker, attending his third pro-Palestinian protest.
