Air raid sirens wailed and panicked residents ran for cover in Tel Aviv, Israel's commercial and cultural capital. Israel responded by moving troops and heavy weapons toward Gaza and authorizing the call-up of tens of thousands of reservists. There was no word on where the two rockets aimed at Tel Aviv landed, raising the possibility they fell into the Mediterranean. A third rocket landed in an open area on the southern outskirts of Tel Aviv.
The fighting, the heaviest in four years, came after Israel launched a ferocious air assault Wednesday to stop repeated rocket fire from Gaza. The powerful Hamas military chief was killed in that strike, and another 18 Palestinians have died over two days, including five children. Some 100 Palestinians have been wounded. Israeli warplanes struck dozens of Hamas-linked targets in Gaza on Thursday, sending loud booms echoing across the narrow Mediterranean coastal strip at regular intervals, followed by gray columns of smoke. After nightfall, several explosions shook Gaza City several minutes apart, a sign the strikes were not letting up, and the military said the targets were about 70 underground rocket-launching sites.
Israeli Prime Minister Benjamin Netanyahu said the army was hitting Hamas hard with what he called surgical strikes, and warned of a "significant widening" of the Gaza operation. Israel will "continue to take whatever action is necessary to defend our people," said Netanyahu, who is up for re-election in January. There were mounting signs of a ground operation. At least 12 trucks were seen transporting tanks and armored personnel carriers toward Gaza late Thursday, and a number of buses carrying soldiers arrived. Israeli TV stations said a Gaza incursion was expected on Friday, though military officials said no decision had been made.
Defense Minister Ehud Barak said he authorized the call-up of reservists, and the army said up to 30,000 additional troops could be drafted. "We will continue the attacks and we will increase the attacks, and I believe we will obtain our objectives," said Lt. Gen. Benny Gantz, Israel's military chief.
