Palestinian militants in the Gaza Strip fired a projectile at southern Israel on Thursday without causing casualties or damage, a police spokesman told AFP.
"Earlier today, a rocket was fired out of Gaza Strip, it landed in the Negev region," Micky Rosenfeld said. "As of now, no injuries or damages were reported."
The last incident of cross-border fire between Israel and the Islamist Hamas-ruled Gaza was on June 24, when the radical Islamic Jihad group fired five rockets at Israel, which retaliated with air strikes.
No organisation immediately claimed responsibility for Thursday's attack.
As the ruling authority, Hamas is responsible for ensuring that militant movements respect the terms of the truce brokered by Egypt, which ended a major eight-day confrontation with Israel in November.
