Venezuelan President suffers new infection
Venezuelan President, Hugo Chavez, is suffering from a new, severe respiratory infection following cancer surgery.
Information Minister, Ernesto Villegas, said President Chavez's condition continued to be very delicate.
Mr Villegas read out the latest brief update on national television.
Speaking from the Caracas military hospital where Mr Chavez is being treated, Mr Villegas said: "Today there is a worsening of respiratory function."
He said President Chavez was undergoing "intensive chemotherapy, as well as complementary treatments."
"The commander-president remains clinging to Christ and to life, conscious of the difficulties that he is facing, and complying strictly with the programme designed by his medical team," Mr Villegas said.
President Chavez, who has been in office for 14 years, is believed to have cancer in his pelvic area but his exact illness has never been disclosed.
He announced in June 2011 that he had cancer and has undergone four operations since then, as well as chemotherapy and radiation therapy.
The president was re-elected for another six-year term in October 2012, but the Supreme Court ruled that his swearing-in on 10 January could be delayed because of his illness.
At the weekend, hundreds of Venezuelan students and opposition members marched in Caracas demanding full details about President Chavez's health.
He is said to be taking decisions about the country from the hospital bed but there have been mixed messages from officials on his condition.
President Chavez, 58, returned to Venezuela last month after being treated for cancer in Cuba, but has not appeared in public since.
