Battle For Misrata Grows Deadlier

Moammar Gadhafi's forces continued attacks on the besieged Libyan city of Misrata Saturday. The city is one of the last holdouts for rebels in the western part of the country. Hundreds of people have been killed in the battle, and this week, two photojournalists died in a rocket attack while covering the fighting. Host Scott Simon speaks with Wall Street Journal reporter Charles Levinson about the ongoing siege of Misrata and NATO's evolving role in Libya.
