Israel steps up Gaza strikes as Netanyahu says Hamas is 'being crushed'

The Israeli military stepped up its campaign of airstrikes Sunday after Prime Minister Benjamin Netanyahu vowed to deliver "painful blows" against Hamas and other militant groups in the Gaza Strip.
"The more determined we remain, the more we demonstrate patience, the sooner our enemies will understand that they will not succeed in wearing us down," Netanyahu said at the opening of his weekly Cabinet meeting. "While they try to tire us out, they are being crushed. I think anyone who observes [the conflict] in recent days understands this concept. The IDF continues to deliver, and to increase, its painful blows against Hamas and the terror groups in the Gaza Strip, and will continue to do this until the goal is achieved."
Among the targets of Israeli strikes early Sunday were a 12-story apartment in Gaza City, as well as a seven-floor office building and severely damaged a two-story shopping center in the southern town of Rafah. 
A senior Israeli military official told the Associated Press that Israel had recently widened the scope of locations that can be targeted on the grounds of housing Hamas operational centers or serving as a starting point for military activities. The official said each strike required prior approval from military lawyers and is carried out only after the local population is warned.
In the 12-story apartment tower, the target was a fourth-floor apartment where Hamas ran an operations center, according to Israeli media. In the past, Israel has carried out pinpoint strikes, targeting apartments in high-rises with missiles, while leaving the buildings standing. However, this time a decision was made to bring down the entire tower, according to Channel 10, an Israeli TV station.
Meanwhile, Gaza militants continued to fire rockets and mortar shells at Israel, including at least 10 on Sunday, the military said. That was in addition to more than 100 on Saturday, most aimed at southern Israel.
Elsewhere, five rockets were fired from Syria and fell in open areas in northern Israel. It was not immediately clear whether they were fired by pro-government forces or rebel groups.
Amid persistent violence, Egypt has urged Israel and the Palestinians to resume indirect talks in Cairo on a durable cease-fire, but stopped short of issuing invitations.
Several rounds of indirect talks between Israel and Hamas have collapsed, along with temporary cease-fires that accompanied them. The gaps between Israel and the Islamic militant group on a new border deal for blockaded Gaza remain vast, and there's no sign either is willing to budge.
The Israeli military said it had carried out some 20 strikes on Gaza since midnight Saturday.
