The first ever game between South Sudan and Sudan ended goalless at the Cecafa Senior Challenge Cup in Ethiopia.
South Sudan's defensive tactics paid dividends as they held on for a point.
After beating Djibouti 2-0 in their opening Group C game on Monday it puts South Sudan in line to qualify for the quarter-finals of the tournament.
"We are happy that we have picked a point against a strong Sudan side," said South Sudan's goalkeeper Juma Ginaro after the game.
