May 9: The Israeli military said Wednesday that it has reopened the Kerem Shalom crossing into Gaza, a key terminal for the entry of humanitarian aid that was closed over the weekend after a Hamas rocket attack killed four Israeli soldiers nearby.

But the United Nations agency for Palestinian refugees said no aid has yet entered and there is no one to receive it on the Palestinian side. Workers fled during an incursion by an Israeli tank brigade on Tuesday that captured the nearby Rafah crossing between Gaza and Egypt, which remains closed.

That limited incursion did not appear to be the start of the full-scale invasion of Rafah that Israel has repeatedly promised. But the prolonged closure of the two main crossings could exacerbate the humanitarian crisis in Gaza, where the U.N. says a “full-blown famine” is already underway in the north.

The United States paused a shipment of bombs to Israel last week over concerns that Israel was approaching a decision on launching a full-scale assault on Rafah, in a further widening of divisions between the two close allies.

The U.S. says it is concerned over the fate of around 1.3 million Palestinians crammed into Rafah, most of whom fled fighting elsewhere. Israel says Rafah is Hamas’ last stronghold and that a wider offensive there is needed to dismantle the group’s military and governing capabilities.

The U.S., Egypt and Qatar are meanwhile ramping up efforts to close the gaps in a possible agreement for at least a temporary cease-fire and the release of some of the scores of Israeli hostages still held by Hamas. Israel has linked the threatened Rafah operation to the fate of those negotiations. (AP)
