Three men from central England appeared in court Thursday to be accused by prosecutors of taking part in an alleged plot to attack Britain's far-right English Defense League.

Anzal Hussain, 24, Mohammed Saud, 22, and 22-year-old Zohaib Ahmed appeared Wednesday at Westminster Magistrates' Court charged with preparing an act of terrorism, which carries a potential life sentence.

Deputy Chief Magistrate Daphne Wickham ordered the three men from Birmingham, central England, held in prison custody until a hearing on July 31.

On Tuesday, three other men were also ordered held. All six will appear together at the hearing at London's Central Criminal Court.

Prosecutors allege that the men were involved in manufacturing an improvised explosive device and planned to attack a rally of the English Defense League.

The English Defense League claims to be a peaceful opponent of radical Islam, but opponents accuse the organization of racism.
