Early trade in New York: Euro remains vulnerable to Greece worries

The euro fell to a three week low on Wednesday and is likely to remain pressured by ongoing concerns about whether euro zone officials will provide timely financial aid to debt-laden Greece and Portugal. In Greece, police fired teargas at dozens of youths hurling stones in central Athens on Wednesday. A strike against austerity brought much of the nation to a halt during talks on the next slice of a bailout package.
The euro dropped 1.4 percent to $1.4203 with the session low at $1.4195, its weakest since April 18. Sterling was last little changed against the dollar. The dollar was also little changed against the yen at 80.84 yen but up 0.8 percent against the Swiss franc at 0.8862 francs.
