On May 22, 5,000 Northern Sudanese troops invaded Abyei, violating several peace agreements with South Sudan. It only took two days for the Northern Sudanese army to overrun the South Sudanese troops with a combined aerial and infantry campaign. According to UN estimates, the invasion forced 25,000 - 30,000 individuals to flee the area. This invasion could represent an effort by Khartoum to gain a firm foothold in Abyei before the formal declaration of independence by South Sudan on July 9.
