Here in New York, at least 26 people were arrested Wednesday as they blocked an expressway leading to JFK Airport in a nonviolent civil disobedience protest demanding a ceasefire in the Gaza Strip. Protesters linked arms and held banners reading “Right to Return, Right to Remain” and “Divest from Genocide,” snarling traffic to New York’s busiest airport for about 20 minutes during the busiest travel week of the year. In Los Angeles, 36 people were arrested at a simultaneous protest that blocked traffic near Los Angeles International Airport.
