A British couple have been convicted of plotting a terror attack in London.
It comes after the husband sent out tweets asking for advice on which targets he should hit, alerting police to a stockpile of chemicals at their home.
Mohammed Rehman, 25, and Sana Ahmed Khan, 24, were found guilty of engaging in the preparation of terrorist acts, with a view to hitting either a large shopping centre in the capital or the London underground network.
The couple, who denied the charges, are to be sentenced at the Central Criminal Court on a later date.
Britain is on its second highest alert level of "severe", meaning an attack by militants is considered highly likely.
