Venezuelan President Hugo Chavez
Venezuelan President Hugo Chavez says he has returned to the country after receiving treatment for cancer in Cuba.
In three messages posted on Twitter, Chavez, 58, thanked Cuban President and ex-leader Raul and Fidel Castro.
He thanked Venezuelans for their support and said he would continue treatment in his home country, reports the BBC.
He has been president for 14 years and was re-elected for another six-year term in October 2011, but his swearing-in was delayed because of his illness.
Chavez went to Havana for surgery on December 11, his fourth operation in an 18-month period for cancer first diagnosed in mid-2011.
Last week the first images of him since his surgery were broadcast by Venezuela's government.
He was pictured smiling as he lay in bed reading a newspaper, with his two daughters by his side.
The extent of Chavez's illness is shrouded in mystery, but it is understood to be serious.
During his treatment the Venezuelan leader is reported to have had tumours removed from his pelvic region.
He has also undergone prior rounds of chemotherapy and radiation treatment.
Though there have been few details about the president's exact treatment, Vice-President Nicolas Maduro described it as "extremely complex and tough".
