Israeli Prime Minister Benjamin Netanyahu said on Sunday that the country's recent attacks on the Gaza Strip had "collected a high price" from Palestinians.
The three-day bombing campaign has killed at least 18 people, including a 12 year-old boy.
Netanyahu said the attacks were justified and promised to continue attacking for the foreseeable future.
"We have collected a high price from them and we are still collecting," Netanyahu said at a cabinet meeting. "We will continue to operate as long as it is necessary."
