JERUSALEM: Gaza militants fired a rocket that exploded in the yard of a residential building in the southern Israeli town of Netivot on Friday, police told AFP, the latest in a wave of tit-for-tat cross-border fire.

Police spokeswoman Luba Samri said one person suffering from shock was taken for medical treatment. There were no immediate reports of damage.

On Thursday, Israeli warplanes raided a training camp of the Ezzedine al-Qassam Brigades, the armed wing of the ruling Hamas movement, several hours after Gaza militants fired two rockets into southern Israel.

On Wednesday the Israeli air force hit targets in northern Gaza, also without causing casualties. A small group of radical Salafists in a statement sent to AFP had said it fired rockets was in response to air strikes on Gaza.

Earlier this week, the armed wings of Hamas and Islamic Jihad fired a barrage of projectiles at southern Israel a day after warplanes raided the southern city of Rafah, targeting two men the military said were global jihad activists.

The two were critically wounded and one later died of his injuries. Another eight people were wounded, among them five children.

Monday's rocket fire by Hamas and Islamic Jihad militants marked a rare show of force given that the two group normally observe a de facto truce on rocket fire on Israel.

The last time Hamas militants fired on Israel was during a flareup in June when militant groups fired more than 150 rockets, wounding five people, and Israel hit back with air strikes that killed 15 Palestinians.
