A group of Chinese dissidents filed a lawsuit in federal court Tuesday accusing Yahoo Inc. and two former general counsels of misdirecting millions of dollars from a fund set up to provide humanitarian aid.

The plaintiffs, represented by Cohen Milstein Sellers & Toll attorney Times Wang, are Chinese citizens formerly detained for speaking out against their government. In 2007, Yahoo created a $17.3 million trust fund to provide financial assistance to imprisoned Chinese dissidents as part of a settlement in a prior lawsuit.
