At least 23 people were killed across Gaza, Palestinian officials said on Wednesday in what may be the start of a lengthy offensive against Islamist militants whose rockets struck deeper than ever before into Israel, according to The Associated Press.
Israelis ran for cover late on Tuesday as air-raid sirens sounded in the business capital Tel Aviv and the holy city of Jerusalem, both of which were hit in the Gaza war of November 2012, the AP reported.
Hamas said it also fired a rocket at the major northern city of Haifa, 88 miles away, and though this was not confirmed, Israel said a rocket had landed in Hadera, 60 miles from Gaza, further than had previously been reached, according to the AP.
While the Israelis reported no casualties, the long-range salvo was celebrated by the outgunned Palestinians as proof of their resolve in hostilities that flared three weeks ago after the abduction and murder of three Jewish seminary students, the AP reported.
The rocket strikes could lead to an Israeli ground invasion, something officials have said is a possible option.
In the densely populated Gaza Strip, explosions echoed day and night, shaking buildings and sending up plumes of smoke, according to the AP. At least 17 civilians, including five children, were among the 23 dead, Palestinian officials said. On the Israeli side, at least two people were wounded, medics said.
Israel assassinated a senior local leader of the Islamic Jihad militant group in the northern Gaza Strip early on Wednesday, neighbours and hospital officials said, and five others including family members were killed, the AP reported.
Since Israel launched its offensive on Tuesday, five Hamas gunmen, an Islamic Jihad leader and 17 civilians, including seven children, have been killed, according to the AP.
