The BBC reported people in Abidjan, the western African nation's largest city, largely ignored the call to disrupt the economy by not showing up for work. The strike gained some momentum in the north, the British network said.

The predominantly Muslim north backs Ouattara, while the primarily Christian south supports Gbagbo.
RFI reported Ouattara supporters rallied peacefully at their country's embassy in Paris.
Ouattara has won international recognition as the winner of last month's presidential election over incumbent Laurent Gbagbo, who has refused to step down.

Leaders from Benin, Cape Verde and Sierra Leone are expected to meet with Gbagbo Tuesday to urge him to vacate the presidency.
