The Palestinian Authority (PA) released a Palestinian businessman on Sunday it had arrested upon his return from a U.S.-led economic conference in Bahrain this week, his family and an official said.

The Palestinian leadership boycotted the conference in protest at a U.S. economic plan for Israeli-Palestinian peace, saying it was Trump who had inflicted further hardship on the Palestinians with cuts to aid.

They branded as "collaborators" the handful of Palestinian businessmen who attended the meeting, although Salah Abu Miala, from the city of Hebron in the occupied West Bank, was the only one arrested after returning on Friday.

A brother of Abu Miala, who asked not to be identified by first name, said Abu Miala had been released. "My brother is at home. He is ill. We don't want anyone to talk to him," he said.

A Palestinian official who spoke to Reuters under condition of anonymity said Abu Miala was released overnight between Saturday and Sunday.
