Hundreds of Sudanese marched towards the Egyptian embassy in Khartoum on Thursday to condemn what they described as Egyptian President Abdel Fattah al-Sisi's "interference" in their affairs.
"This is Sudan," marchers chanted. "Your authority ends at [the Upper Egyptian city of] Aswan."
On Sudanese social-media accounts, activists posted video footage showing protesters in central Khartoum chanting angrily against al-Sisi.
On April 11, the Sudanese army announced the ouster of President Omar al-Bashir following months of popular demonstrations against his 30-year rule.
A Military Transitional Council (MTC) is now overseeing a two-year "transitional period" during which it has pledged to hold presidential elections.
The Sudanese opposition, however, has continued to stage demonstrations to demand that the MTC relinquish power -- immediately -- to a civilian government.
On Tuesday, Cairo hosted an African Union (AU) summit, where participants called for giving the MTC a three-month deadline for handing power over to a civil administration.
Egypt currently holds the AU's rotating chairmanship.
Al-Sisi came to power in Egypt on the back of a 2013 military coup against Mohamed Morsi, the country's first-ever democratically-elected leader.
