Villegas said a government-organized New Year’s Eve concert in a downtown Caracas plaza had been canceled, and he urged Venezuelans to pray for Chavez.
Chavez’s daughter Maria, who has been with the president since his surgery, said in a message on her Twitter account: ‘‘Thank you people of Venezuela. Thank you people of the world. You and your love have always been our greatest strength! God is with us! We love you!’’
Allies of the president also responded on Twitter, repeating the phrase: ‘‘Chavez lives and will triumph.’’
