United Nations Security Council Resolution 1907, adopted on December 23, 2009, imposed an arms embargo on Eritrea, travel bans on its leaders, and froze the assets of some of the country's political and military officials after accusing the Eritrean government of aiding Al-Shabaab in Somalia and reportedly refusing to withdraw troops from its disputed border with Djibouti, following a conflict in 2008. The African Union and other organisations had been calling on the Security Council to sanction Eritrea for several months.
