The U.S. and allies are scrambling to pull together a complex system that will move tons of humanitarian aid into Gaza by sea. Nearly two months after President Joe Biden gave the order, U.S. Army and Navy troops are assembling the large floating platform several miles off the Gaza coast that will be the launching pad for deliveries. But any eventual aid distribution — which could start as soon as early next month — will rely on a complicated logistical and security plan with many moving parts and details that are not yet finalized.

A Silicon Valley-backed campaign to build a new city in California for up to 400,000 people says it submitted enough signatures to qualify the initiative for the November election. If Solano County elections officials agree, voters in the San Francisco Bay Area county will decide whether to allow urban development on land now zoned for agriculture. Voters would need to approve the change for the development to be built. Jan Sramek, who heads the company behind the campaign, submitted more than 20,000 signatures to the elections office Tuesday, more than the 13,000 needed. He proposes a development of homes and a walkable downtown. Critics say he should build housing within existing cities.

Colombian President Gustavo Petro says that hundreds of thousands of pieces of ammunition have gone missing from two military bases in the South American country. In a brief statement, Petro says that an inspection carried out this month by the army found that hundreds of thousands of bullets, thousands of grenades and 37 anti-tank missiles were stolen from a military base in the center of the country and another near the Caribbean coast. Petro says the ammunition might have ended up in the hands of Colombian rebel groups, or may have been sold illegally to criminal groups overseas, including Haitian gangs.
