An Arab-American evangelical pastor said Wednesday that he has been threatened by a Palestinian security official in the West Bank city of Ramallah, and has fled to Jerusalem for safety.

Pastor Isa Bajalia, 47, a US citizen born in Birmingham, Alabama, said that he had been threatened over the last two months by a Fatah security official from the Tanzim militia who also demanded $30,000 in protection money. Bajalia said he had moved to nearby Jerusalem since the threats began.

The pastor has been living in Ramallah, considered to be the most liberal of all the West Bank cities under Palestinian control, since 1991, together with his American wife and son, who attended school in Jerusalem and has since joined the US Air Force.

For the last decade he served as pastor for a group of 30-35 people in Ramallah, holding Sunday services in private homes and carrying out missionary work among the Palestinians, who are predominantly Muslim.

Initially, Bajalia said he was treated with respect, but some suspicion, by the locals, and viewed as an outsider coming in with a foreign concept. The pastor said the threats began about two months ago after a group of church workers were seen praying on behalf of Palestinians.

"We will do to you what Hamas did to Fatah in Gaza," Bajalia said the Palestinian security official warned him. Bajalia, who has a vision problem, said he was also told that in addition to his eye problems he would not be able to walk anymore.

The Palestinian security official subsequently told Bajalia to register some of his family's land in the official's name and pay him $30,000, the pastor said. Bajalia said he had also been watched for six months...
