Some witnesses say he shouted ‘Allahu akbar’ (‘God is great’ in Arabic) but the motive for the attack is unclear.

The suspect has been identified as a 27-year-old German national, apparently from the Hessen area of central Germany.

The former Work and Pensions Secretary Iain Duncan Smith has claimed Prime Minister David Cameron failed in his attempt to renegotiate Britain’s relationship with the EU.

Mr Duncan Smith said that Britain was in a worse position that it was before, as our correspondent Chris Delaney explains.

Presidential hopeful Donald Trump says newly elected mayor of London, Sadiq Khan, would be an ‘exception’ to his proposed ban on Muslims entering the US.

Mr Trump said he was ‘happy’ that Mr Khan would be leading London. He then added:

If he does a good job and frankly if he does a great job, that would be a terrific thing.

Last year, the Republic presidential hopeful called for a temporary halt to all Muslims entering the US in the wake of the deadly terror attack in San Bernardino, California.

He said many Muslims nursed a ‘hatred’ towards America and a ban should be in force ‘until our country’s representatives can figure out what is going on.’

Al Riddell explains the comments made by the Republican nominee.

Mr Khan has since dismissed Mr Tump’s comments, saying:

This isn’t just about me. It’s about my friends, my family and everyone who comes from a background similar to mine, anywhere in the world.

Mr Khan also warned that Mr Trump’s ‘ignorant’ views of Islam ‘could make both our countries less safe.’
