Israel will send the chief of its Mossad intelligence agency to Qatar to continue talks over a potential ceasefire-for-hostages deal in Gaza, in a possible sign the negotiations may be advancing.

Mossad director's presence means high-level Israeli officials who would need to sign off on any agreement are now involved. Along with Mossad chief, head of Israel's Shin Bet internal security agency and military and political advisers will also be sent to Qatar to be part of negotiation talks.

It wasn't immediately clear on Saturday when David Barnea would travel to Qatar’s capital for the latest round of indirect talks.
