LAWRENCE, Mass. (AP) The Latest on gas explosions in Massachusetts (all times local):
The CEO of a hospital in one of the Massachusetts communities affected by a series of natural gas explosions and fires says it treated 13 patients.
Dianne Anderson is CEO of Lawrence General Hospital. She says it dealt with injuries ranging from smoke inhalation to blast trauma.

A subsidiary of the parent company of Columbia Gas of Massachusetts was blamed by federal investigators for a 2012 pipeline rupture and explosion in West Virginia.
The explosion destroyed three homes and sent flames shooting into the air. The pipeline was operated by Columbia Gas Transmission Corp., which at the time was owned by NiSource.
NiSource is the parent company of Columbia Gas of Massachusetts, which services three communities where a series of fires and explosions killed a teenager and injured more than two dozen others on Thursday.
The National Transportation Safety Board said that the West Virginia rupture likely could have been prevented if the pipeline had been inspected or tested, but that it hadn't been since 1988.
Investigators also said Columbia Gas Transmission's response to the rupture was delayed.

The 58-year-old man said Friday he came home Thursday to find a note on the door of his apartment building telling everyone to leave because the gas and electricity were being shut off in response to several gas explosions and fires in the town.

One person was killed and about 25 were hurt.

The National Transportation Safety Board is sending a team to Massachusetts to investigate a series of gas explosions blamed for one death and dozens of fires.
An agency spokesman said during a news conference in Washington on Friday that pipelines are within the agency's jurisdiction.
The spokesman says among other things, the agency will look at the design of the pipeline system, maintenance and upgrades that have been done, and the safety record of the pipeline operator.
