Israeli Air Strikes Kill 16

Violence along the Israeli-Gaza frontier escalated again Saturday after Israeli troops killed at least 16 people over the last two days in attacks and airstrikes they say are aimed at weapons-manufacturing sites and at wiping out militants. Palestinians in Gaza fired some 90 rockets into southern Israel on Friday and Saturday, injuring at least eight people, one critically. Half a million people were urged to remain indoors and public events have been cancelled. The violence began Friday when Israeli troops blew up a car in Gaza City, killing two militant leaders who they say were plotting attacks from Egypt.
