Students are protesting over Edinburgh University's investment in fossil fuels and arms.

Campaigners formed a human barrier outside Charles Stewart House on Friday morning, blocking the building's entrance.

They claim more than £6m of the university's endowment was invested in those industries as of November 2015.

Protesters have threatened to take further action if Edinburgh University fails to commit to fully divesting itself by Easter.

The university previously said it would no longer invest in companies which take more than 20% of their turnover from arms sales.

Campaigner Hannah Roques said: "The Paris climate summit has only reinforced the message that civil society must lead the way to a safer and more sustainable future.

"Our public institutions are crossing red lines by failing to take immediate action on the climate and we must now hold them to account."

The protest was organised as part of Go Green Week 2016, seven days of action aimed at awareness about fossil fuel and arms investment.

A spokesman for Edinburgh University said: "This week the University ratified its responsible investment policy statement, which will ensure that we use our finances to make a significant, sustainable and socially responsible contribution to Scotland, the UK and the world.

“In line with our new policy statement, we do not invest in companies involved in the highest carbon-emitting industries. Last summer we divested millions of pounds from three of the world’s biggest fossil fuels producers.

“Last September, we also confirmed we do not, or never will invest in companies involved in controversial weapons and any company who derives 20% of its profit from armaments."
