Earlier Sunday, dozens of aid trucks entered Gaza from southern Israel under a new agreement to bypass the Rafah crossing with Egypt after Israeli forces seized the Palestinian side of it earlier this month. Israel’s military said 126 aid trucks entered via the nearby Kerem Shalom crossing.

But it was not immediately clear if humanitarian groups could access the aid — including medical supplies — because of fighting. The crossing has been largely inaccessible because of Israel’s offensive in Rafah. United Nations agencies say it is usually too dangerous to retrieve the aid. The World Health Organization last week said an expanded Israeli incursion in Rafah would have “disastrous” impact.”
