UPDATE: A senior Hamas official in Cairo, Moussa Abu Marzouk, said late Wednesday, "There is no agreement on an extension of the truce," according to Reuters.

ORIGINAL: Israel has conditionally agreed to extend a 72-hour ceasefire with Hamas beyond Friday, Reuters reported on WednesdayThe news service quoted an Israeli official speaking on the condition of anonymity.

"Israel has expressed its readiness to extend the truce under its current terms."

However, there has been no indication of how long that extension would be. The three-day truce brokered by Egypt was holding on Wednesday, unlike a similar ceasefire in the month-long conflict that collapsed within hours last week.

The two sides were preparing for talks on a longer-term peace deal. Those negotiations, which will be led by Egypt with help from the U.S., were expected to center on security arrangements and trade access to the Gaza Strip, according to the Wall Street Journal.

Israel will demand that Hamas completely disarm, while the Palestinians want Israel to lift its blockade of the Gaza Strip.

The fighting has killed 1,875 Palestinians and 67 Israelis, according to a Journal tally.
