Tel Aviv/Gaza City - Israel killed four Palestinian militants in an airstrike near Gaza City Sunday morning, hours after Palestinians launched rockets at Israeli border towns.
In a further indication that a five-month-old truce between Israel and the Gaza militias is fast collapsing, Israeli Premier Ehud Olmert said he has ordered the military to submit a plan to "restore full quiet to the south", and the Islamist Hamas movement, which controls the Gaza Strip, said it would "respond heavily to any Zionist offensive or attacks against our people."
