At least three Palestinians have been killed after Israel conducted an air raid on the Gaza Strip.

Medical workers said two people were killed at the scene of the attack on Thursday near the Israel-Gaza border and a third died later in hospital.

An Israeli army spokesman said the raid targeted a group of fighters who had fired an anti-tank missile at troops across the border.

Shortly after the attack, three rockets fired from the territory landed in southern Israel, the military said.

There were no reports of casualties.

The Islamic Jihad claimed responsibility and vowed to continue its attacks against Israel.

"Our rockets and our resistance will not stop," Abu Ahmed, an official of the armed Palestinian group, said.

Sporadic fighting

Thursday's attack was the second targeting the territory in less than 24 hours by Israeli forces.

A raid killed two Islamic Jihad members, including a field commander for the group, the previous day.
 
While Egypt has been trying to broker a lasting ceasefire between the two sides, following Israel's 22-day offensive on Gaza, fighters have continued to carry out sporadic attacks.

Israel has responded with air raids targeting suspected smuggling tunnels on the Gaza-Egypt border.
