LONDON, April 22 (Reuters) - European shares hit a 3-week closing low on Thursday, with banks slipping as Greek's debt concerns resurfaced and Nokia <NOK1V.HE> dropping after it cut its profit outlook.
Investment sentiment was dented after Eurostat said the Greek government posted a budget deficit worse than had been feared, while a Moody's Investors Service downgrade of Greece's sovereign rating added to investor worries.
The pan-European FTSEurofirst 300 <
> index of top shares closed down 1.1 percent at 1,083.88 points, after earlier having been up as much as 1,102.69 points.Banks extended their slide from the previous session. Greek banks <.FTATBNK> slipped 5.4 percent, while Banco Santander <SAN.MC>, BBVA <BBVA.MC>, HSBC <HSBA.L>, BNP Paribas <BNPP.PA> and Societe Generale <SOGN.PA> fell 0.7 to 3.1 percent.
"Today it is a Greek story. The market seems to be pricing in some default or restructuring," said Mike Lenhoff, chief strategist at Brewin Dolphin.
"The Moody's downgrade is another part of the saga. Each time we have some sort of announcement and get closer to a resolution, there seems to be another stage to overcome."
Credit Suisse <CSGN.VX> lost 4.7 percent after first-quarter results failed to match the blowout numbers from major U.S. banks disappointing investors.
Nokia sunk more than 14 percent to its lowest close in 8 weeks after it cut its profit outlook and delayed the launch of phones it needs to compete with the iPhone and Blackberry. [
