Sudanese activists are preparing for a “milioniya” – a call for millions-strong mass protests – on 30 June, amid growing fears that the military council is planning a further bloody crackdown.

The Sudanese Professionals Association has called for mass marches and civil disobedience. Over the past few days the SPA Facebook has shared footage of mobilising protests and declarations by different professional groups pledging to join the protests.

But the authorities have also seized a leading figure in the protest movement, arresting Yassin Hassan Abdelkarim, president of the Teachers’ Committee, a key independent union from his house early on 28 June. Leading Sudanese activists told Middle East Solidarity that fears are growing of further arrests and violence against the demonstrations, following the massacre on 3 June.

Sudanese activists around the world are planning solidarity protests on 30 June and urging trade unionists and campaigners to join in or follow the movement on social media.

What you can do:

• Join the protest at the Sudanese embassy in London, 12 noon 30 June, moving to Richmond Terrace (outside Downing St) around 3pm
• Look out for local protests in other towns and cities around the UK
• Write to your MP and call on them to demand that the Transitional Military Council is held to account for the massacre on 3 June and that the UK stops all arms sales to Saudi Arabia and the UAE who are backing the military in Sudan.
