"We wish you the best; you are a reference of courage and dignity for revolutionaries. Let's continue fighting for the happiness of our peoples. A hug," Maduro wrote on his Twitter account.
For his part, Carlos Fonseca Terán, secretary of international relations for the Sandinista National Liberation Front (FSLN), highlighted his party's leader's name with a video clip of his inauguration as president in 2007.
On that occasion, the late President of Venezuela Hugo Chávez called Ortega one of the indispensable men, as he belongs to the group of those who fight for their entire life.

"With great joy, we celebrate the birthday of Commander Daniel Ortega, our great brother, and Sandinista leader. We wish you the best; you are a reference of courage and dignity for revolutionaries. Let's continue fighting for the happiness of our peoples. A hug!"
The organization of young communicators Juventud Presidente also recalled on the same social media platform that Ortega, one of the greatest revolutionary leaders of recent times in Latin America and the world, was born in La Libertad department Chontales, on this day in 1945.
Another user called El Socialista expressed that we celebrate all and every Nicaraguan who loves peace, tranquility, and security in our blessed and always free homeland.
Ortega participated since he was very young in the emancipation struggles of his country and joined in the guerrilla fight, in which he achieved a military rank and remained until the overthrow of the dictatorship of Anastasio Somoza with the triumph of the Sandinista Revolution in 1979.
At that time, he assumed the country's leadership until 1990 and later returned to the highest office when the FSLN triumphed in the 2006 elections with a large majority.
