Four Israeli soldiers were wounded when a device exploded Saturday at the southern Gaza border in an attack that was quickly retaliated by Israeli forces.
Earlier in the day, the IDF said that an explosive device was detonated against IDF troops adjacent to the security fence near the southern Gaza Strip.
At least four Israeli soldiers were injured when a patrol was hit in an IED explosion in the Gaza Strip.
Israeli sources said that israeli jets bombed six Hamas positions in Gaza and Palestinian factions fired tow rocket into Israel at night.
In response, an IDF tank fired at a Hamas watchtower near the border. "We will respond appropriately and I send my wishes for a quick recovery to the wounded".

Israel's Radio's military correspondent called the incident "serious and irregular", according to the Times of Israel.
There was no immediate claim of responsibility for the explosion, but army spokesman Jonathan Conricus blamed the Islamist Palestinian movement Hamas for the blast, in remarks on Twitter.
Warnings sirens wailed throughout numerous Gaza border communities Sunday night amid escalating violence between Israel and the Palestinians in the coastal Strip.
Earlier this month, Chief of Staff Gadi Eisenkot alerted ministers during a cabinet meeting of the growing possibility of another war with the Gaza-based group amid the worsening humanitarian crisis in the territory.
Dozens of Palestinians demonstrators have been injured in recent weeks along the border fence with Gaza, with the Israeli army using live fire to disperse protesters.
