Venezuela's President, Hugo Chavez, is suffering from "complications" brought on by a "severe lung infection" which developed after surgery, officials say.
Mr Chavez, 58, had his fourth operation for cancer in Cuba on 11 December and then developed a respiratory infection.
In a statement from Caracas, Information Minister Ernesto Villegas said the infection had "led to a respiratory insufficiency".
The president has not been seen in public since having cancer surgery in Havana, prompting persistent speculation about his condition.
