Sri Lanka: David Cameron met by demonstrations in Jaffna

The Prime Minister's convoy has been mobbed by demonstrators in northern Sri Lanka, who are protesting against alleged human rights abuses by the government.

David Cameron drove through Jaffna, surrounded at times by scores of people carrying photographs of loved ones they claim were murdered in the final stages of the civil war.

He is in Sri Lanka to attend a summit of Commonwealth leaders.
