Nonprofit groups are working to secure housing for Hurricane Katrina victims still living in abandoned buildings, says National Public Radio.

The organization Unity of Greater New Orleans has searched more than 1,300 vacant buildings since December looking for squatters. Martha Kegel, the group’s executive director, said many disabled and poor residents ended up on the streets when post-storm federal housing aid was exhausted.

Unity is starting a new program in October, financed with federal stimulus money, to provide short-term rental and job assistance for about 2,000 households in New Orleans.

Also, CNN reports on the unprecedented entertainment-industry involvement in Katrina-related charity.
