Struggling French carmaker PSA Peugeot-Citroen is slashing 8,000 jobs in France and closing an iconic site north of Paris. Union members said company management announced the job cuts and closure plan during a meeting with the works council. The restructuring plan includes the closure of its Aulnay-sous-Bois factory. Unions vowed to try to fight back, and plan protests later Thursday. The company is trying to save €1 billion ($1.2 billion) this year as it struggles to compete in Europe's fiercely competitive car market. It is suffering particularly amid a slump in sales in the recession-hit south of Europe. Its sales plunged 20 percent in Europe in the first quarter. It is hoping a new alliance with General Motors Corp. will allow it to return to long-term profitability.
