The White House continued Wednesday to avoid direct criticism of Israel's military actions in Gaza, including its massive airstrike on a refugee camp, saying it wouldn't respond to each development on the battlefield.
Speaking aboard Air Force One, National Security Council spokesperson John Kirby said instead the US was in constant conversation with the Israelis about the importance of protecting civilian lives.
"We’re going to be cautious about reacting to each and every event on the ground," Kirby told CNN, adding the US was still gathering details on the strike.
He could not provide American estimates of causalities.
Kirby declined to elaborate on US President Joe Biden's personal reaction to the airstrike, which occurred Tuesday.
He said the US has long been concerned about the imperative to protect civilians.
"There's not a conversation we're having with our Israeli counterparts that doesn't reflect our continued concern over civilian casualties and urging them to be as careful and deliberate as possible to avoid that risk," he said.
"You'll continue to hear from the president about our significant concern over civilian harm," Kirby added later.
