Some 100 writers, including Pulitzer Prize-winning Alice Walker, Richard Ford, and Junot Diaz, have urged the PEN American Centre to reject any support from Israel as it denies “basic rights to the Palestinian people.”

The writers sent an impassioned letter to PEN American Centre in March but it became public only on Wednesday. PEN American Center, created in 1922, is a group aiming to promote literature and support literary fellowship.
