Senior officials from the United States, Qatar and Israel are expected to join the third day of talks between Israel and Hamas in the Egyptian resort of Sharm el-Sheikh. It's a sign negotiators aim to tackle on Wednesday the toughest issues of an American plan to end the war in Gaza. Hamas says it's seeking solid guarantees from U.S. President Donald Trump that Israel will not resume its military campaign after the militant group releases its remaining hostages under the plan. Among the more senior officials joining the negotiations are Qatar’s prime minister, Trump’s Mideast envoy Steve Witkoff and the U.S. president’s son-in-law, Jared Kushner. Prime Minister Benjamin Netanyahu’s top adviser, Ron Dermer, is also to join.

The United Nations has reimposed sanctions on Iran over its nuclear program. That further squeezes the Islamic Republic as its people increasingly find themselves priced out of the food they need to survive and worried about their futures. After last-minute diplomacy failed at the U.N., the sanctions took effect Sunday at 0000 GMT. The sanctions will again freeze Iranian assets abroad, halt arms deals with Tehran, and penalize any development of Iran’s ballistic missile program, among other measures. It came via a mechanism known as “snapback,” included in Iran’s 2015 nuclear deal with world powers.
