At around 10:30 p.m., IDF gunship launched several missiles at an area used by the Abu-Reish Brigades, located west of the al-Amal neighborhood in Khan Younis.

A spokesman for the Abu Reish brigades said his organization will respond quickly and painfully to Israel's strike in Gaza.

"The blood of our dead shall not be spilled in vain – retaliation will come quickly," he said.

Spokesman for the Palestinian government, Dr. Razi Khamed said in response to the attack that "Israel is a terror state that should disappear and be isolated. We are surprised by the European stance in light of this escalation initiated by Israel. The attack in Khan Younis is another ugly Israeli crime."

A spokesman for Palestinian Authority Chairman Mahmoud Abbas also condemned the strike on behalf of Abbas, and said that the Palestinians plan to raise the issue before the U.N. Security Council.

According to military officials, the strike's target was used for shooting practices and for activating explosive devices. A senior officer told Ynet that the army intends to continue putting pressure on terror organizations in the Strip and target Qassam launching cells.
