A grand jury has handed down an 11-count indictment against three NATO-summit protesters jailed since May, including four terrorism-related counts and half a dozen new charges, according to the document obtained by The Associated Press from defense attorneys.

Tacking on more charges to three original charges could give prosecutors more leverage in negotiating a plea deal later or in boosting their chances of securing at least some convictions if the case does eventually go to trial, some legal experts said Wednesday.
