Steve Witkoff, President Donald Trump's special envoy to the Middle East, interviewed on ABC's 'This Week' program, addressed nuclear talks with Iran and the humanitarian situation in the Gaza Strip. Regarding Iran, Witkoff said the president wants to resolve this 'through diplomacy and dialogue': 'But we have a red line, and that's uranium enrichment - we cannot allow even 1% of enrichment capability.' As for the humanitarian situation in Gaza, he said 'Trump is concerned about the humanitarian situation in the Strip, but it's a logistically complex situation, and the conditions on the ground are dangerous. I think there is complete agreement between Trump and Netanyahu.'
