European shares bounced back from near one-month lows on Tuesday, helped by a rise in Siemens after the German engineer posted higher first quarter profits, Reuters reported. But concerns about a sell-off in emerging markets lingered. The pan-European FTSEurofirst 300 index, which had fallen for the last three sessions to its lowest level in more than a month, bounced 0.5 percent to 1,296.35 points in early session trading. The euro zone's blue-chip Euro STOXX 50 index advanced 0.6 percent to 3,032.46 points. A 1.2 percent rise in Siemens added the most points to the FTSEurofirst 300.
