WASHINGTON (Reuters) – Negotiations underway in Cairo to achieve a ceasefire in Gaza will continue on the working group level for the next few days as parties try to iron out some specific issues, White House national security spokesperson John Kirby (NYSE:) said on Monday.

One of the issues that will be tackled by the working groups will be around the exchange of hostages Hamas is holding and Palestinian prisoners, Kirby said. The exchange of fire between Israel and Hezbollah over the weekend has not had an impact on the talks in Cairo, he added.
