Israel's prime minister says he will not cave in to international pressure to stop a military offensive in the Gaza Strip. Benjamin Netanyahu told a news conference Friday that Israel will continue its offensive until rocket fire out of Gaza is halted. He says he has had ``good conversations'' with a number of world leaders in recent days, including President Barack Obama and European leaders. ``No international pressure will prevent us from acting with all power,'' he said. Netanyahu said Israel has attacked more than 1,000 targets in Gaza during the four-day operation and is using twice the force it used during a similar offensive in 2012. More than 100 Palestinians have been killed.
