A suspected U.S. drone strike killed four members of al Qaeda's Yemen branch, including a local commander, two unidentified officials in Yemen said Saturday. A vehicle traveling east of the capital Sanaa was reportedly hit by the drone. Officials told Reuters the attack was carried out in Marib province, which is controlled by forces loyal to exiled President Abd-Rabbu Mansour Hadi, late Friday. Abu Khaled al-Sanaani, the local commander of Al Qaeda in the Arabian Peninsula (AQAP), was among the four dead, officials said. The latest attack was the second drone strike in two days to target a local commander of the militant group, which is regarded by U.S. officials as one of the most dangerous branches of al Qaeda.

The Flybrix team didn't set out to build an adorable DIY mini-drone out of Lego bricks. But as any road-tripper can tell you, sometimes the journey turns out to be more fun than the destination. Amir Hirsch has a masters from MIT. Robb Walters has a PhD from Cal Tech. And Holly Kasun has a marketing background that spans from Nike to Nokia. Together, they set out to make small drones smarter, not STEM toys.

One of the world's largest package delivery companies is stepping up efforts to integrate drones into its system. UPS has partnered with robot-maker CyPhy Works to test the use of drones to make commercial deliveries to remote or difficult-to-access locations. The companies began testing the drones on Thursday, when they launched one from the seaside town of Marblehead. The drone flew on a programmed route for 3 miles over the Atlantic Ocean to deliver an inhaler at Children's Island. The successful landing was greeted by jubilant shouts from CyPhy Works and UPS employees on the island to witness the test. "I thought it was fantastic," said John Dodero, UPS vice president for industrial engineering.

LEGOs get knocked down, and then they get put back together again. Drones, with few exceptions, get put together, and are then gravely damaged beyond repair when they crash. Why not build on the repairability of LEGO bricks when making a hobbyist drone?

United Parcel Service Inc. UPS -0.42 % said Friday it successfully used a drone to deliver medicine to an island near Boston, jumping into a race with competitors such as Amazon.com Inc. AMZN 0.13 % to test drone delivery inside the U.S. The delivery of an inhaler on Thursday was conducted in partnership with CyPhy Works, a drone maker in which UPS holds a stake. The delivery kicks off a wider test by UPS of using drones for commercial deliveries to remote or difficult-to-access areas. "UPS has a history of trying to take a look at new technologies as they evolve," said Chuck Holland, a vice president of industrial engineering. "We're looking at this in steps," he added, declining to say whether the company may someday use drones more broadly.

United Parcel Service (UPS) is newest competitor in the race to unleash the first fleet of delivery drones. The firm began testing the use of drones this week with a focus of bringing packages to remote or difficult-to-access locations. A mock delivery of urgent medical supplies was delivered from Beverly, Massachusetts to Children's Island as a test, which is the first drone delivery to be made by a major delivery firm in the US. United Parcel Service (UPS) is newest competitor in the race to unleash the first fleet of delivery drones. UPS announced today that it has begun testing the use of drones to make commercial deliveries of packages to remote or difficult-to-access locations, working together with drone-maker CyPhy Works.

Remember when Amazon announced Prime Air drone delivery back in 2013? Following the excited hubbub, other services including UPS scrambled to try out competitive airbone services. But then everyone ran into a slew of logistics and regulations issues, which have taken years to untangle. In the past few months, Google was given FAA approval for drone deliveries and Amazon might bypass regulation entirely for its air shipping. But UPS is going in a different direction: Testing UAVs to ferry emergency medical supplies.

Newly revised federal aviation regulations don't permit commercial drones to fly over people not involved in their operations and require them to remain within line of sight of their operators, effectively rendering commercial deliveries impossible. Drone-makers are working with regulators to tweak existing rules.
