France is to seek a vote in the UN Security Council to impose an arms embargo and other bans on the Ivory Coast.
The move comes after a ceasefire in the Ivory Coast was broken and nine French soldiers were killed by government bombings.
The vote was delayed last week to give African Union officials a chance to negotiate a truce between rebels, who control the north of the country, and the government, which holds the south.
A summit among West African leaders in Nigeria yesterday backed the arms embargo and asked that it be imposed immediately.
