Many residents here expressed fear that unless the perpetrators were caught and calm was restored, the delicate web of coexistence that binds Tuba-Zangariya and the neighboring Jewish collective farms and towns north of the Sea of Galilee could be ruined. On Thursday an Israeli court remanded one suspect, a Jewish youth, in connection with the burning of the mosque, but he has not yet been charged. The suspect’s lawyer identified him as an 18-year-old seminary student with ties to one of the staunchest Jewish settlements in the West Bank, The Associated Press reported.

“We are the only Bedouin town in the area, surrounded by Jewish neighbors,” said Ali Heib, 31, a member of one of the two large clans in Tuba-Zangariya, describing the intricate relationship as one of mutual dependency. “We work in their places.”

Mr. Heib was sitting with dozens of other villagers under an awning in the forecourt of the mosque a day after the blaze. They drank coffee, received a stream of visitors from nearby Arab and Jewish communities and held afternoon prayers in the open air.

The arson attack followed a series of similar assaults on mosques in West Bank Palestinian villages. Hebrew graffiti scrawled at the charred entrance of the mosque here bore the stamp of radical Jewish settlers in the West Bank and their sympathizers, calling for revenge for a Jewish settler who was killed last month along with his infant son after their car overturned in the West Bank. Israeli officials said that the crash occurred after the car was stoned by Palestinians.

The messages seemed incongruous here, in the mostly tranquil Galilee. Israeli leaders hastened to condemn the act. The president, Shimon Peres, ministers and the country’s chief rabbis have visited the mosque in a show of solidarity.
