KINGSTON, Jamaica (AP) - Masked men and security forces are trading gunfire in a barricaded slum in Jamaica's capital.
      
A police station is burning after gunmen lobbed fire bombs at it, sending black smoke spiraling into the sky.
      
The government has declared a state of emergency.

Defiant supporters of alleged drug kingpin Christopher "dudus" Coke have transformed a part of West Kingston into a virtual fortress cut off by trashed cars and barbed wire.

Local media say least two people have been wounded in Sunday's violence, including one police officer.

The U.S., Canada and Britain issued travel alerts Friday warning of possible violence and unrest in Jamaica. Most islanders have been avoiding downtown Kingston entirely.
