A blue wave has spread across thousands of social media profiles to honour the memory of a victim of the brutal crackdown on protesters in Sudan.
Engineer Mohamed Mattar, 26, was allegedly fatally shot by the Sudanese paramilitary Rapid Support Forces during the 3 June attacks. He was reportedly trying to protect two women at the time.
His favourite colour was blue, prompting the social media movement.
What started as a touching tribute to Mr Mattar from friends and family has now grown into a broader movement of solidarity with Sudan, as the world tries to piece together the violence taking place in the country.
Local media has been largely blocked from covering the unfolding violence, by the government.
Violence first erupted in the North African country earlier this month when armed men in military fatigues broke up a weeks-long, sit-in protest outside army headquarters in Khartoum. The protest, which began on 6 April, was first called for the ousting of veteran leader Omar al-Bashir.
After his removal, protesters called for the removal of the replacement military council.
