Almost universal support for the unprecedented three minute silence is expected as the world struggles to comprehend the enormity of the events in New York, Washington D.C. and Pittsburgh.
The silence will be observed across Europe after the European Union announced today was to be an official day of mourning.
Earlier in the week, Ford Motor Company closed all of its plants in the U.S. and Canada in the wake of the terror attacks across the Atlantic.
The manufacturer closed its World headquarters in Dearborn, Michigan, and regional offices in New York City and Washington D.C. as a precautionary measure following the terrorist attacks.
Ford said nearly all of its facilities in the U.S. and Canada reopened on Wednesday, with the exception of offices in New York City and Washington D.C.
GM released this statement: “The sympathy and support of the company and its employees is with the American people. As part of a globally operating corporation, management and the workforce of General Motors in Europe express their deepest sympathy for the victims, their families and all those affected.”
As a token of solidarity, production at all of GM's European operations was halted at midday on Wednesday for a minute's silence.
Toyota Motor Manufacturing, also with offices in both New York and Washington, suspended the second-shift at all of its plants on Tuesday and stopped domestic and international travel.
The full extent of the impact on the global automotive industry of Tuesday's attacks has yet to become clear.
