MANILA, Philippines >> Police say robbers at a convenience store in the Philippine capital have shot dead an American executive of an English language training center.

Police say Robert Edward Armstrong was inside the Manila store on Sunday when four robbers ordered the employees and at least three customers into the storage room while they emptied the cash register. Police officer Alonzo Layugan says 45-year-old Armstrong was shot when he tried to dash out of the store.

Layugan said Monday that the wounded American managed to get into his car but one of the robbers shot him again. Armstrong was declared dead at a hospital. His hometown was not immediately known.

Police say the other customers and employees were unharmed. The robbers are still at large.
