UNITED NATIONS — The U.N. Security Council has approved an arms embargo and other tough sanctions against Eritrea for supplying weapons to opponents of the Somali government and refusing to resolve a border dispute with neighboring Djibouti.

The U.N.'s most powerful body adopted a resolution Wednesday imposing the measures by a vote of 13-1, with Libya voting "no" and China abstaining.

The resolution bans the import and export of weapons to Eritrea and calls on U.N. member states to inspect all suspect air and sea cargo between the Red Sea nation and Somalia.

Dec. 23 (Bloomberg) -- Eritrean government and military leaders accused of being allied with al-Qaeda-linked terrorists in a bid to topple Somalia’s transitional government became the target of United Nations sanctions today.

The UN Security Council voted 13-1 to ban the travel and freeze the assets of Eritreans designated by a committee of the 15-nation panel. The measure imposes an arms embargo on Eritrea, authorizes inspection of cargo going to or from the country on the Red Sea, and demands that it settle a border dispute with Djibouti.

Libya was the only nation to vote against the resolution, which was drafted by Uganda. China abstained from the vote.

Eritrea denies funding the insurgency in Somalia

The UN Security Council has imposed sanctions on Eritrea because of aid it says it has been giving to Islamic insurgents in Somalia.

The resolution places an arms embargo on Eritrea, and also imposes travel bans and asset freezes on businesses and individuals.

Members of the Eritrean leadership are expected to be affected. The resolution was backed by 13 votes to 15.

China abstained while Libya, the only Arab council member, voted against.

Eritrean officials have repeatedly denied the allegations, calling them a "fabrication" of US intelligence.
