Italian industrial output rebounded 2.8% in September after a 2.7% drop in August, data showed on Wednesday, offering some hope to the country's long-struggling manufacturing sector. A Reuters survey of 12 analysts had pointed to a 1.5% increase. On a work day-adjusted year-on-year basis, industrial output in the euro zone's third largest economy rose 1.5% in September, national statistics agency ISTAT said. That compared to a forecast of an 0.5% decrease and followed a 3.0% fall in August.
