Hamas has said it did not want the Gaza ceasefire agreement to collapse, Reuters reports.

Mediators are exerting pressure for the deal to be fully implemented, ensure Israel abides by a humanitarian protocol and resume exchanges of Israeli hostages held in Gaza for Palestinian prisoners and detainees held by Israel on Saturday, Hamas said in a statement.

Israel has called up military reservists to brace for a possible re-eruption of war in Gaza if Hamas fails to meet a Saturday deadline to free further Israeli hostages.
