Colombia rescuers seek survivors in collapse that killed 10

Rescuers say they're searching for survivors in the wreckage of a half-built structure that collapsed in the northern Colombian city of Cartagena and killed at least 10 people.
National emergency officials say that so far 23 people are listed as injured.
The seven-story building collapsed as workers were putting down a layer of cement yesterday.
Local Civil Defense head Mauricio Rodriguez says more than 100 rescue workers continue to hunt for survivors trapped under the debris.
The national prosecutor's office says it's looking into whether the project had all needed permits and if workers were covered by health insurance.
