The European Union's foreign policy chief is urging the U.N. Security Council to adopt a resolution allowing the EU maritime force, charged with seizing migrant-smuggling vessels off Libya's coast, to help enforce an arms embargo on the North African nation.

Federica Mogherini told the council on Monday that EU ships have saved lives, seized vessels and traffickers — and should now also help stop arms shipments headed to Libya.

Russia's U.N. Ambassador Vitaly Churkin said Moscow was not opposed to the idea but had "some concerns," especially about the response of the rival factions in Libya where a fledgling U.N.-backed government still faces opposition.

Churkin said "the highest priority" in Libya should be to make sure Parliament approves the new national unity government, which Russia expects to happen "soon."
