Israeli aircraft have fired missiles into the Palestinian Authority's Gaza City compound, near to the offices of President Mahmoud Abbas.
The two missile attacks wounded two Palestinians and left deep craters on a landing strip close to the Palestinian Authority offices.
Mr Abbas was reportedly at his offices in the West Bank at the time.
The Israel military confirmed the attack, but said it was targeting militants who fire rockets into Israel.
The army said the strike came in response to several homemade Palestinian rocket attacks fired on southern Israel earlier on Tuesday.
A spokeswoman said they wanted to "send a message" to the Palestinians that such attacks would not be tolerated, the AFP news agency reported.
Mr Abbas' spokesman condemned the attacks and called on the US and the West to intervene.
"This escalation will lead the area to more violence and instability," Nabil Abu Rdeneh said.
