Updated below: Facebook is continuing to raise money, though this one seems to be a relatively smaller amount and mainly strategic for European expansion: it has taken an undisclosed amount of investment from German Internet entrepreneurs, the three Samwer Brothers, who run their own venture capital firm, the European Founders Fund. The three brothers Alexander, Marc and Oliver Samwer started a German auction site which later became eBay (NSDQ: EBAY) Germany and then founded the mobile content giant Jamba, which was later bought by Verisign for $273 million. The company’s portfolio includes supposed Facebook-rival LinkedIn as well, so would be interesting to see how this gets balanced.

Update: WSJ reports that the amount is between $10 million to $15 million.
