RAMALLAH (Ma'an) -- The condition of a woman arrested over her critical writings about President Mahmoud Abbas is deteriorating in isolation, a member of the Palestinian Journalists Syndicate said Tuesday.

Ismat Abdul Khaliq was seen by doctors late Tuesday before being returned to her cell, said Nihad Abu Ghosh, a member of the syndicate. He said the prosecution is refusing to let her see visitors.

Prosecutors accuse Abdul Khaliq of writing a Facebook status update criticizing Abbas. She has been held since last week after a court extended her detention for 15 days along with a newspaper reporter.

The arrest followed a complaint by the preventive security service, PA officials have said.

Abdul Khaliq was one of two Palestinians arrested in a week for Facebook updates criticizing Abbas, Human Rights Watch said Tuesday. Two news reporters have been detained during the same period.
