More than two dozen U.S. insurers affiliated with Travelers Cos (TRV.N) have sued two Saudi banks, companies affiliated with Osama bin Laden's family, and several charities for at least $4.2 billion over the Sept. 11, 2001 attacks.

The lawsuit filed late on Wednesday night in the U.S. District Court in Manhattan is the latest effort to hold entities in Saudi Arabia liable for the attacks.

Nearly 3,000 people died when hijacked airplanes crashed into New York's World Trade Center, the Pentagon near Washington, D.C. and a Pennsylvania field.
