GAZA CITY, Gaza Strip – Israeli tanks and troops launched a ground offensive in the Gaza Strip Saturday night with officials saying they expected a lengthy fight with Hamas militants in the densely populated territory after eight days of punishing airstrikes failed to halt rocket attacks on Israel.
Hamas vowed that Gaza would be a "graveyard" for Israelis forces.
"This will not be easy and it will not be short," Israeli Defense Minister Ehud Barak said soon after the ground invasion began.
The incursion was preceded by several hours of heavy artillery fire after dark, igniting flames in the night sky. Machine gun fire rattled as bright tracer rounds flashed through the darkness and the crash of hundreds of shells sent up streaks of fire.
Artillery fired illuminating rounds, sending streaks of bright light drifting down over Gaza's densely packed neighborhoods. Gunbattles could be heard, as troops crossed the border into Gaza, marching single file. They were backed by helicopter gunships and tanks.
Israeli security officials said the objective is not to reoccupy Gaza. The depth and intensity of the ground operation will depend on parallel diplomatic efforts, the officials said on condition of anonymity because they were not authorized to speak to the media.
We have many, many targets, Israeli army spokeswoman Maj. Avital Leibovich told CNN. "To my estimation, it will be a lengthy operation."
Before the ground incursion began, heavy Israeli artillery fire hit east of Gaza City in locations were Hamas fighters were deployed. The artillery shells were apparently intended to detonate Hamas explosive devices and mines planted along the border area before troops marched in.
"Gaza will not be paved with flowers for you, it will be paved with fire and hell," Hamas warned Israeli forces. Spokesman Ismail Radwan said in a televised speech Gaza will "become a graveyard" for Israeli soldiers.
