Palestinian militants targeted densely populated Tel Aviv in Israel's heartland with rockets for the first time Thursday, part of an unprecedented barrage that threatened to provoke an Israeli ground assault on Gaza.
Three Israelis -- two men and a pregnant woman -- were killed in the southern Israeli town of Kiryat Malachi.
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 yesterday, 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.
At least 12 trucks were seen transporting tanks and armored personnel carriers toward Gaza late yesterday, and a number of buses carrying soldiers arrived. Israeli TV stations said a Gaza incursion was expected today, though military officials said no decision had been made.
Hamas, meanwhile, warned it would strike deeper inside Israel with Iranian-made Fajr-5 rockets, acknowledging for the first time it has such longer-range weapons capable of hitting targets some 47 miles away. Tel Aviv is 40 miles from Gaza.
By nightfall Thursday, Hamas said it had fired more than 350 rockets into Israel. Israel said some 220 rockets struck the Jewish state and another 130 were intercepted by an anti-missile shield.
