PORTLAND, Maine (AP) Another wave of African asylum seekers is headed to Portland.

Portland officials say they’re expecting about 70 Africans to begin arriving later this week. The Portland Press Herald reported that the city is preparing contingency plans.

The numbers will be smaller than in the summer, when several hundred Africans arrived from the southern border. The city set up an emergency shelter at the Portland Expo, and organizations frantically worked to find homes for the newcomers.

The arrival of families fleeing Angola, Congo and other countries showed that it’s not just Central Americans making the journey to the southern U.S. border.

Portland City Manager Jon Jennings said he has been in communication with officials in San Antonio about the anticipated arrival of dozens of new asylum seekers.
