Hundreds of Ugandan students are demonstrating against the European Union parliament, after it opposed an oil pipeline project with neighbouring Tanzania.
EU lawmakers earlier this month passed a resolution warning of human rights abuses and the social and environmental risk posed by the project.
The students are marching in the capital, Kampala, to deliver a petition to the EU mission.
The demo appears state-sanctioned and the students are walking with police escort.
Once complete, the pipeline will stretch 1,443km (896 miles) from Lake Albert in western Uganda to the Tanzanian port of Tanga on the Indian Ocean.
