Three members of the same family have been jailed for terror offences after police foiled a jewellery raid they believe was intended to fund Islamic State of Iraq and the Levant (Isil).

Asma Aweys, 30, her partner Abdulaziz Abu Munye, 27, and her brother Ahmed Aweys, 33, were all arrested when police investigating a burglary plot found terrorist propaganda on their mobile devices.

In one message, Aweys, a mother-of-two from Edmonton in north London, labelled Ariana Grande as "the devil" in relation to the Manchester bombing and described the Westminster terror attack as the "decree of Allah."

Aweys was also found to have three copies of the English language IS magazine Rumiyah on her phone last April.

Articles in the publications offered advice such as how to "inflict misery and destruction on the enemies of Allah" through methods including vehicle attacks.
