TEHRAN, May 26 (Xinhua) -- Iranian President Hassan Rouhani on Saturday congratulated his Venezuelan counterpart Nicolas Maduro for his re-election, state TV reported.

In a message to Maduro, Rouhani hailed the election in Venezuela as "successful, peaceful and fair," saying it was a "great victory" for the Latin American nation.

"Without a doubt, the successful, peaceful and fair election, under economic sanctions and threats by foreign powers, is considered a great victory and achievement for the government and people of Venezuela," Rouhani said.

Iran is hopeful about further expansion of the "cordial and all-out" relations through joint efforts during Maduro's presidency, he added.

Last week, Maduro secured a second six-year term in the Venezuelan presidential election.
