JERUSALEM — Across the Gaza Strip on Monday morning, loudspeakers on minarets urged Palestinians to rush the fence bordering Israel, where they were met by army snipers. At least 60 were killed and thousands injured, local officials said — the worst day of carnage there since Israel invaded Gaza in 2014.

Hours later, a beaming Ivanka Trump helped unveil a stone marker etched with her father’s name on the new American Embassy in Jerusalem, keeping his campaign promise to officially acknowledge Jerusalem as Israel’s capital. An audience of 800 religious conservatives and right-wing politicians from both countries sang “Hallelujah.”

“What a glorious day,” exulted Prime Minister Benjamin Netanyahu.

The two scenes, only an hour’s drive apart, illustrated the chasm dividing Israelis and Palestinians more than at any moment in recent history.
