LONDON - A 35-year-old mother has been jailed for five years and three months for posting extremist information on Facebook and WhatsApp, a local court in London heard Thursday.

Kingston Crown Court heard that Runa Khan, a mother of six children, had reposted a web article instructing mothers to prepare their children for radical acts.

A judge said the article was like "a manual in encouraging women to carry out jihad," according to a BBC report.

Investigators also found that Khan had taken pictures of her underage children holding a toy gun and a sword.

She was also found to have posted a photo of a suicide vest and expressed intention to travel to Syria.

Investigators said Khan had hoped that her son would one day become a "jihadist fighter", and employed social media as a tool for "terrorism".

In August, Britain upgraded its international terrorism threat level from "substantial" to "severe," the second highest of five possible threat ranks.

The British Home Office has introduced a series of tougher counter-terror measures this year to tackle international terrorism.
