Mohamed Abu Reda was killed when an Israeli aircraft fired at least one missile on his house in the village of Khuvaa, near the southern town of Khan Younis, the sources told Agence France-Presse (AFP).
Two people were also wounded in the attack.
The dead and wounded were family members and were not resistance fighters, witnesses told Reuters.
Residents in Khuvaa said Israeli troops had pushed deeper into the village and had detained 10 people.
An Israeli military source said the troops were operating in the area as part of ongoing operations there.
Earlier residents said an Israeli force had briefly detained the head of the village municipality, Kamal Annajar.
Annajar, also a Hamas local leader, was later released, they added.
Hours earlier, Israeli warplanes carried out two air strikes in the southern Gaza Strip city of Rafah, killing four Hamas members.
An Israeli drone fired a missile at a vehicle in the city, killing Ali Issa al-Nachar and Aid al-Bashiti.
At least 25 people were injured when the drone fired a second missile on people who gathered around the bombed-out car.
Later, an Israeli drone fired two rockets at a vehicle carrying Hamas activists Abdel Karim Ashur and Abul-Abd al-Arqan, killing them instantly.
More than 200 Palestinians have been killed and thousands others wounded since Israel launched a wide-scale blitz in Gaza on June 12, on the claim of seeking the release of a soldier taken prisoner by Palestinian groups to swap with Palestinian women and children in Israeli jails.
The new deaths bring to 5,381 the number of people, mostly Palestinians, killed since the outbreak of Al-Aqsa intifada in September 2000, according to an AFP tally.
