Three people from Brighton have denied helping a man accused of plotting to kill and cause explosions on London's transport system on July 21 last year.

They are among four men and two women who also denied various charges of failing to disclose information on terrorism.

They are due to stand trial on February 12 next year.

Hussain Osman is one of five men charged with conspiracy to murder, conspiracy to cause explosions likely to endanger life and having an improvised explosive device with intent to cause an explosion likely to endanger life.

He is also accused of the attempted murder of passengers on the Transport for London system.

The 27-year-old, from London, denies all the charges.

Osman's wife, Yeshiemebet Girma, 29, her sister, Mulumebet Girma, 21, and their brother, Sayas Girma, 20, all from Stockwell, south London, and Shadi Abdelgadir, 23, Omer Almagboul, 21, and Mohamed Kabashi, 24, all from Brighton, are accused of "assisting an offender" - Osman - and "failing to disclose information about acts of terrorism".

They entered not guilty pleas before Mr Justice Fulford during a 90-minute hearing at Woolwich Crown Court.

Yeshiemebet Girma was remanded in custody while the other five were released on conditional bail.

Osman was arrested after bombs in rucksacks failed to go off at London Underground stations and a bus on July 21.

Another device was found in bushes near Wormwood Scrubs, west London. He is due to stand trial, along with four other men, on October 3.
