GAZA CITY (CNN) -- An Israeli airstrike Wednesday hit a Hamas post in southern Gaza, killing two Hamas security men in Khan Yunis, according to Hamas sources.
Hamas members in Gaza City watch TV coverage of the Mideast summit on Tuesday.
The Israeli army said the airstrike -- the third in Gaza this week -- was in response to the firing of mortars into Israel.
According to the Israeli military, 11 mortars and Qassam rockets were fired into Israel on Wednesday.
Reacting to incessant rocket attacks from Gaza, Israel's government labeled the Hamas-controlled region a "hostile territory" in September, setting in motion a wide-ranging crackdown that includes military operations and limiting Gaza's power supply.
Gaza militants fire rockets into Israel every three hours, on average, according to the Israeli military.
Speaking at the Mideast peace summit in Annapolis, Maryland, on Tuesday, Israeli Prime Minister Ehud Olmert said "the continued shooting of Qassam rockets against tens of thousands of residents in the south of Israel, particularly in the city of Sderot, serves as a warning sign -- one which cannot be overlooked."
He said the ongoing attacks are a hurdle to achieving peace with the Palestinians and are the result of "the absence of governmental institutes and effective law enforcement mechanisms" in Hamas-ruled Gaza. E-mail to a friend
