American car giant General Motors has said a lack of parts from Japan is forcing the company to halt production at a pick-up assembly plant in the US next week.
It is the first time a US-based car maker has slowed production in North America because of disruptions in parts shipments after last week's earthquake and tsunami in Japan.
Toyota and Subaru have already slowed production at their North American plants to conserve stockpiles of parts.
GM's other North American plants have not been affected so far.
The company would not say which parts are involved, adding that it would resume resume production as soon as possible.
GM employs 800 factory workers in Shreveport, Lousiana, which makes the GMC Canyon and Chevrolet Colorado small pick-ups.
