DOHA (Reuters) - Qatar's prime minister on Sunday called on Israel and Hamas to immediately begin negotiating phase two of the Gaza ceasefire, adding that there is no clear plan for when talks will begin.

It is believed that at least two of the six American hostages still held in Gaza are alive — Sagui Dekel-Chen, 35, who grew up in Bloomfield, Connecticut, and Edan Alexander, 19, from Tenafly, New Jersey. Four other Americans are believed to have been killed in captivity.

The visuals out of Israel and Gaza during recent hostage-for-prisoner swaps were part of a choreographed battle of optics waged in parallel to the 16-month ground war between Israel and Hamas. Each side uses the light and shadow of images to make themselves look virtuous and strong — and each other monstrous and weak.
