AL AMARI REFUGEE CAMP, West Bank — Maher al-Naden, a street cleaner, said he had stopped buying Tapuzina, a popular Israeli orange-flavored drink, and Israeli dairy products.

“This is the least we can do,” he said this week, expressing frustration as a West Bank Palestinian who is essentially a spectator of the war in Gaza. Across the alley from where he stood, in this teeming refugee camp abutting Ramallah, a small Internet cafe called Facebook bore a new-looking sign with a silhouette of a masked, armed fighter.

More than two weeks into the deadly fighting between Israel and Hamas in Gaza, here in the realm of the Western-backed Palestinian Authority, daily life has continued more or less as normal, punctuated by nighttime clashes at friction points around the West Bank between stone-throwing youths and Israeli forces.

On Thursday night, thousands of Palestinians marched from Al Amari to the Qalandia checkpoint that separates Ramallah from Jerusalem, many carrying Palestinian flags and wearing black T-shirts with the slogan, “We are all Gaza.” Some middle-class families came with children; in the front lines, dozens of masked young men hurled stones and firecrackers and clashed with Israeli security forces, roaring, “With our soul and blood, we will redeem Gaza.”
