Two sisters have been charged under anti-terror laws for failing to disclose information connected with the July 21 failed London [Images] suicide bombings.

Sisters Yeshshiembet Girma (29) and Muluemebet Girma (21) of Stockwell in south London are slated to appear at the Bow Street Magistrates Court in London on Friday, Scotland Yard said on Thursday.

The women were arrested on July 27 and have been charged under Section 38 of the Terrorism Act 2000, they said.

The sisters are accused of 'having information that they knew or believed might be of material assistance in securing the apprehension, prosecution or conviction of another person in the United Kingdom for an offence involving the commission, preparation or instigation of an act of terrorism, failed to disclose that information as soon as reasonably practicable to a constable' between July 21 and July 28.

Ismael Abdurahman, the first man to be similarly charged in connection to the failed attacks, was remanded to custody
on Thursday at Bow Street Magistrate's Court.

He was charged with having failed to disclose information about a suspected bomber.

In a brief hearing lasting just under 10 minutes, Abdurahman spoke only to give his name.

District Judge Timothy Workman remanded him to custody until August 11. Police are holding a total of 15 people over the failed suicide attacks.
