Two U.S. service members were killed and six more wounded during an attack on a joint operation between American and Afghan forces on Saturday in eastern Afghanistan.

From a launch pad at the Kennedy Space Center on Sunday, Elon Musk's SpaceX launched its latest rocket test into the Florida sky. Less than two minutes later, it exploded — just like the company hoped it would.

The explosion itself wasn't so much the success as was what came just before it. That's when the Crew Dragon, a capsule meant to carry astronauts into space, separated from the rocket. That separation was the goal of Sunday's test.

Five people are dead and at least 60 more are injured after a multivehicle crash along the Pennsylvania Turnpike early Sunday morning.

Limani said the crash was similar to a chain reaction and involved a bus operated by the Z&D Tour company.
