Lebanese turning on Hezb Allah?

YNet:

The IDF has found that Hizbullah is preventing civilians from leaving villages in southern Lebanon. Roadblocks have been set up outside some of the villages to prevent residents from leaving, while in other villages Hizbullah is preventing UN representatives from entering, who are trying to help residents leave. In two villages, exchanges of fire between residents and Hizbullah have broken out.

If true, can you think of anything more evil than trapping families in a target zone? Who can doubt that Hizbullah must be crushed?
