Israeli troops early on Sunday killed two Hamas activists on the northern border of the Gaza Strip, the armed wing of the Islamist movement announced.
"Two of our fighters were killed in an exchange of fire" with the Israeli army, the Ezzedin Al-Qassam Brigades said.
Palestinian medical sources said the two men were killed near the electric fence surrounding the Gaza Strip, near Beit Lahiya.
The Israeli army confirmed the clash. A military spokesman told AFP that soldiers had spotted two armed men near the fence and opened fire on them, "killing or wounding them."
The latest deaths bring to 5,790 the number of people who have died since the start of the second Palestinian uprising in September 2000, the vast majority of them Palestinians, according to an AFP tally.
