AMMAN, OCTOBER 27 - Police authorities launched a crackdown campaign against homosexual men who gather in public places in Amman as part of official efforts to fight "immoral behavior," a police source said today. Four gay men were arrested earlier this week after they were ambushed by secret service in a public garden in west Amman, the source was quoted by al Ghad Arbic daily today. "The men were each kept in solitary confinement at Jweideh prison, south Amman, in order to separate them from other prisoners to avoid sexual relation with other inmates," said the police source. The four men, whose names were kept secret due to sensitivity of the issue in this tribal country, remain in prison without charges and authorizes refuse to release them on bail. Amman military governor, Saad Manasir vowed to continue the campaign "until all forms of sexual misconduct are ended." The governor has the right to send citizens to prison for two months without charges "if he felt their freedom represents danger the society," according to the Jordanian law. "Homosexuality is on the rise in Jordan and they have certain gathering areas as they look for a chance to practice immoral actions," the police source was quoted as saying, as he indicated number of homosexuals is believed to be 600. Jordan's law bans homosexuality and any man caught having sex with another man faces up to four years behind bars, but the law is rarely practiced.
