The word “tragic” cannot even begin to describe the Israeli airstrike that set fire to a tent camp in the Gaza Strip’s Rafah, killing 45 Palestinians, US Vice President Kamala Harris said tonight.

The comment came while Harris was answering a question from a reporter, following Sunday’s Israeli shelling of the camp and an evacuation zone in West Rafah, where 21 people were killed today, according to the Palestinian enclave’s health services. The events are yet another test of President Joe Biden’s pledge not to arm the US ally if it went ahead with a large-scale operation that would put displaced people in Rafah at risk.

Harris, who made the statement at a ceremony in Washington, did not respond to a follow-up question about whether Israel’s attacks on Rafah constitute a violation of the US “red line”.

The State Department today expressed its “deepest sorrow” for the Palestinians killed Sunday in Rafah, noting that the results of the Israeli military’s investigation are awaited, with the hope that the investigation will be done “swiftly and transparently.”

State Department spokesman Matthew Miller stressed that Washington will continue to stress to Israel that it is obligated to fully comply with international humanitarian law, minimize the consequences of its operations on civilians and maximize the flow of humanitarian aid. to those who need it.
