US President Donald Trump said he had "good discussions" with Russian leader Vladimir Putin when they met briefly at an Asia-Pacific summit in Vietnam.

On Twitter, he blasted "haters and fools", who, he said, do not encourage good relations between the countries.

Earlier he said Mr Putin told him he was insulted by allegations of Russian interference in the 2016 US election.

The US intelligence community has previously concluded that Russia tried to sway the poll in Mr Trump's favour.
