The All-Party Parliamentary Inquiry into anti-Semitism wants prosecutors to examine if prevention orders like those used to restrict sex offenders' internet access could be used.

The cross-party group also highlighted the use of anti-Semitic terms online.

Last week, a Community Security Trust report said UK anti-Semitic incidents more than doubled to 1,168 in 2014.

The trust - which monitors anti-Semitism in Britain - says this was its highest figure recorded since it began work in 1984.

'Hate crimes'

The Parliamentary inquiry was set up following a rise in incidents in July and August last year during fighting between Gaza and Israel.

The MPs said social media platforms had "increasingly been used for the spread of anti-Semitism".

Their report said the terms "Hitler" and "Holocaust" were among the top 35 phrases relating to Jews during the conflict.

The hashtags "Hitler" and "genocide" featured with "high frequency", it added. The "Hitler Was Right" hashtag trended worldwide in July 2014.

The rise in violent anti-Semitic attacks last year in the UK was clearly linked to the conflict in Gaza, with some using criticism of Israel's actions as a pretext for hate speech.

Although the Jewish community is deeply integrated into British society, many British Jews say there has always been a low level of underlying anti-Semitism - such as casual, thoughtless remarks - but the rise of hate speech online is new and risks normalizing such sentiments.

Extremist or hate speech against one minority creates an environment in which such sentiments can easily spread to others. So today's call may also be welcomed by Muslim communities, facing what they say is a rise in Islamophobia following the Paris attacks.

Despite all that, the UK is still seen as one of the most tolerant places in the world to live. MPs, peers and others are keen to ensure that remains the case.
