Israeli fighter jets conducted an airstrike in the southern Gaza Strip early Thursday, according to eyewitnesses.
The airstrike reportedly hit a target belonging to the Ezzedine al-Qassam Brigades, the military wing of Hamas, west of Khan Yunis.
There were no casualties, the sources added.
The Palestinian Health Ministry has not released a statement so far.
Tensions have been high near the Gaza-Israel fence amid ongoing rallies by Palestinian demonstrators demanding the right to return to their homes in historical Palestine.
The rallies are also aimed at breaking the decade-long Israeli/Egyptian siege of the Gaza Strip.
More than 230 Palestinian demonstrators have been martyred by Israeli army gunfire since the Gaza rallies began on March 30.
