The Israeli army says its tanks have hit Hamas targets in the Gaza Strip on Sunday after Palestinian balloon attacks across the border continued.
An early-morning military statement said there had been airborne explosive and incendiary attacks into southern Israel on Saturday.
There were no immediate reports of casualties from any of the incidents.
Palestinian sources said an Israeli artillery shell was fired towards a field control point east of Khan Younis, and another shell east of Deir al-Balah in the central Gaza Strip.
