Egypt on Tuesday denounced Israeli overnight air strikes on an overcrowded neighborhood in Gaza City as a "war crime".
"It is absolutely a war crime as the attacks clearly target innocent civilians," Egyptian Foreign Minister Ahmed Maher told reporters.
He said that "shelling civilians and killing women, men and children is a new evidence of aggressive Israeli policies."
"Strangely enough, the attacks came at a time when reports said that the Palestinian National Authority (PNA) and (the Islamic Resistance Movement) Hamas were ready to declare an agreement on halting all attacks on the Israelis that might harm civilians," Maher said.
"It shows that one of the aims of the Israeli attacks is to torpedo this agreement that would expose an Israeli excuse to continuously occupy the Palestinian lands," the foreign minister stressed.
At least 12 people were killed and 130 others injured in the Israeli air strikes, Palestinian medical sources said.
In addition, Salah Shehada, commander of Hamas' armed wing Izel Dein Al Qassam, as well as his wife and three of their children were among the dead.
Earlier in the day, the PNA appealed to the United Nations Security Council to hold an urgent meeting to condemn the Israeli air strikes.
