GAZA CITY, Gaza Strip (AP) — Ignoring international appeals for a cease-fire, Israel widened its range of Gaza bombing targets to civilian institutions with suspected Hamas ties and deployed ground troops inside Gaza for the first time early Sunday to raid a rocket launching site in the Palestinian territory. More than 156 Palestinians have been killed.

Four Israeli soldiers were hurt in clashes during the brief incursion to destroy a rocket launching site in northern Gaza, the military said. It said the troops later returned to Israeli territory.
