Six men have pleaded not guilty in a UK court in connection with terrorism charges.

The men, all from Birmingham, face an allegation that they took part in activities including the manufacture of an improvised explosive device, the acquisition of firearms and other weapons and the purchase of motor vehicles connected with the charges.

Jewel Uddin, 27, Omar Mohammed Khan, 28, Mohammed Hasseen, 23, Anzal Hussain, 24, and Mohammed Saud and Zohaib Ahmed, both 22, all appeared via prison video link at Woolwich Crown Court in southeast London.

They are jointly accused of preparing an act or acts of terrorism between 1 May and 4 July 2012.

Mohammed Hasseen is also accused of possessing a document or record containing information of a kind likely to be useful to a person committing or preparing an act of terrorism on 3 July, which he also denied.

The charges follow a series of arrests by the West Midlands Counter Terrorism Unit, assisted by the North East Counter Terrorism Unit.

Three of the men were arrested after a routine stop of a car by police on the M1 near Sheffield on 30 June.

It was alleged that a cache of weapons was found in that vehicle along with a note addressed to the English Defence League, which was planning a rally in South Yorkshire that day.

The men spoke only to confirm their names and enter their pleas and were remanded in custody until a further hearing at the court on 25 March.

A provisional trial date has been set for 7 May.
