- Ummariyat Mirza, 21, accused of planning terrorist attack with a knife
- He was also charged with possessing bomb making guide 'Anarchist Cookbook'
- West Midlands Police also charged Zainub Mirza with sending ISIS propoganda videos and execution films to others to 'encourage terror attacks'
A man has been charged with plotting to carry out a terror attack armed with a knife, police said.
Ummariyat Mirza was arrested by counter-terror police on Alum Rock Road, Birmingham, last week.
The 21-year-old, from Birmingham, is accused of buying a blade and conducting research to carry out a deadly assault.
Officers also charged Zainub Mirza, 23, from Bordesley Green, believed to be his sister, with sending Islamic State propaganda videos and executions to others.
It is alleged she sent the extremist material, including a picture of a man holding two severed heads, to encourage terror attacks.
The arrests, made on March 29, were said not to be linked to the Westminster attack last month, in which four people died after a terrorist drove his car into crowds and fatally knifed a police officer.
Five homes and one business address were searched by counter-terrorism officers as part of the investigation, police said.
The pair will appear before Westminster Magistrates' Court on Thursday.
