BOSTON (AP) — More suspected drone sightings in the eastern U.S. led to a temporary airspace shutdown at an Air Force base in Ohio and arrests near Boston’s Logan International Airport, as elected officials increased their push for action to identify and stop the mysterious unmanned flights.

Wright-Patterson Air Force Base in Dayton, Ohio was shut down for four hours due to drone activity, with no airplanes allowed in or out of the base, and officials have attempted to reassure the public that military installations are able to detect and respond to drones.
