Authorities say lasers were pointed at several aircraft in the Boston area overnight, including several commercial flights and a MedFlight that had just taken off from a Boston hospital.

No one was hurt, but laser lights can blind a pilot and pointing them at aircraft violates federal law.

The Federal Aviation Administration tells WBZ-TV it received reports from six aircraft between midnight and 6 a.m. Wednesday. Most of the aircraft were headed to Logan Airport.

Cambridge police said they received reports on three of the incidents.

The MedFlight was headed back to Hanscom Air Force Base.
