Israel and Hamas signaled on Saturday they were preparing for the next phase of ceasefire negotiations, as mediators pushed ahead with talks to extend the fragile 42-day truce that began in January. Hamas said there were "positive indicators" for the start of the ceasefire's second-phase talks but did not elaborate.

Israel carried out an air strike on militants in northern Gaza on Sunday, rattling an already fragile ceasefire as it prepared for fresh talks in Doha on the future of its truce with Hamas.

A high-level Hamas delegation arrived in Cairo to advance efforts on a fragile ceasefire in Gaza, which has largely paused hostilities with Israel, two senior Hamas officials have said.
