JERUSALEM (Reuters) - The wife of a Jewish extremist suspected of planning to throw a pig's head into a Moslem shrine in Jerusalem said on Sunday she was launching a hunger strike to protest at the way authorities were treating her husband. Police are holding Avigdor Eskin and another Jewish extremist on suspicion of planning the desecration in order to ignite clashes between Arabs and Jews. Esther Eskin said police and the Shin Bet security service were harassing her husband because of his political views. Police arrested Eskin and Haim Pakovich last week and barred them from seeing attorneys for several days. Eskin is a high-profile activist in extreme right-wing circles. He was convicted earlier this year of putting a religious curse on Yitzhak Rabin weeks before the Isreali leader was assassinated in Novemer 1995. "I am protesting at the fact that they broke into our house in the middle of the night, they abducted a person...they are holding him in unreasonable conditions and barred him from seeing a laywer for more than a week," Esther Eskin said. "This morning I am launching a hunger strike." Police said on Friday that the suspects planned to throw a pig's head onto the Temple Mount during Islam's holy fasting month of Ramadan which begins this week. The Temple Mount complex in Jerusalem's Old City houses the Dome of the Rock and al-Aqsa mosque, Islam's third holiest shrine. The two shrines are situated on ground where Judaism's ancient sacred temple was razed by the Romans in AD 70, just above the Western Wall, the holiest Jewish site in the world. Prime Minister Benjamin Netanyahu said on Saturday Israel was cracking down on extremists. Islam and Judaism view pigs as unclean and ban the eating of pork. Last June a Jewish woman touched off a wave of Moslem rage by pasting posters on Arab shop windows in the West Bank city of Hebron depicting the Moslem Prophet Mohammad as a pig stamping on the Koran.
