Catalysis of the ligation of two substances via a phosphoric ester bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate. Catalysis of the formation of a phosphodiester bond between a hydroxyl group at the end of one RNA chain and the 5'-phosphate group at the end of another. Catalysis of the reaction: ATP + ribonucleotide (n) + ribonucleotide (m) = AMP + diphosphate + ribonucleotide (n+m).
