Israel said it would send negotiators to the meeting. Hamas initially said it was studying the offer but has now hinted it may stay out of the new round of talks.

Hamas said Israeli actions, including what Hamas has said was its assassination of the group's leader Ismail Haniyeh in Tehran late last month, indicate that Israel is not serious about pursuing a ceasefire agreement. Israel has not denied or claimed responsibility.

President Joe Biden laid out a three-phase ceasefire proposal in an address on May 31.
