Four Hamas activists died late Wednesday in an Israeli air raid and another attack in the Islamist-run Gaza Strip, a Palestinian security source said.
Two activists were wounded and two others died in the air attack, which took place near Khan Yunus in the south of the Gaza Strip, the source said.
The dead were identified as Saher Shahin, 25, and Imad Abou Tuhema, 22. They were members of the Al-Qassam, the armed wing of the Islamist movement.
An Israeli army spokeswoman confirmed the raid to AFP, saying a helicopter attacked "several Palestinian suspects who were approaching the border."
