Israel has called on residents of the northern Gaza Strip to leave their homes, suggesting a coming attack after its troops earlier launched a brief raid.
The Israeli air force dropped leaflets Sunday morning calling for the evacuation.
Israel's military spokesman says troops will begin a ``short and temporary'' campaign against northern Gaza Sunday.
It's not clear whether the possible attack would be confined to stepped-up airstrikes or whether it might include a sizeable ground offensive, something Israel has so far been reluctant to undertake.
The call comes after Israeli troops launched a brief raid early Sunday morning into northern Gaza to destroy what it described as a rocket-launching site.
The military said four soldiers were slightly wounded in the operation.
More than 160 Palestinians have been killed in the six-day offensive.
Militants in Gaza have fired some 700 rockets in Israel during that time, though there have been no fatalities there.
