The United States has said that ally Israel is not doing enough to answer questions a day after a strike in Gaza killed a large number of children, AFP reports.

“They are not doing enough to get us the answers that we have requested,” State Department spokesman Matthew Miller told reporters.

Asked if the US had learned more over the past day since it asked for answers, Miller said, “We reiterated that call with them today. We do not yet have an explanation.”

“They have said to us what they had said publicly, which is they’re investigating the matter,” he said.
