PHOENIX (AP) - Lightning is being investigated as a possible cause of house fires that occurred as a thunderstorm passed through the Phoenix area Friday.
Two of the fires occurred in Phoenix where Fire Department spokesman Mark Vanacore said lightning was "surely a strong consideration."
However, Vanacore said investigators would conduct "a thorough investigative process to ensure that all bases are covered."
House or mobile home fires also were reported in Glendale and Peoria.
No injuries were reported.
