Four NYT journalists missing in Libya *

The New York Times says the Libyan government is helping try to locate Anthony Shadid, Beirut bureau chief; Stephen Farrell, the reporter and videographer who was kidnapped by the Taliban in 2009 and rescued by British commandos; and photographers Tyler Hicks and Lynsey Addario. "We are grateful to the Libyan government for their assurance that if our journalists were captured they would be released promptly and unharmed," executive editor Bill Keller said in a statement. "Their families and their colleagues at The Times are anxiously seeking information about their situation, and praying that they are safe." The four last made contact with the NYT on Tuesday morning.

Added: Two of the missing were previously kidnapped

* Evening update from New York: No change in status. The journalists still have not been heard from since Tuesday. NYT procedure is for reporters to check in multiple times each day and for photographers to contact the desk at least once.
