London faces lockdown to thwart third terror strike by Daniel McGrory and Sean O’Neill

The new group is believed to be made up of British Muslims who were understood to be close to staging an attack on the Underground network last week. According to security sources the men are thought to be of Pakistani origin but born and brought up in this country. They have links with the Leeds-based terrorist cell that staged the July 7 attacks, in which 52 innocent people died.
