I read the news and saw people say it was Uchiha Itachi who was the first to awaken the Mangekyo Sharingan.
Is it true?

This can be shown in the episode "Truth" (真実, Shinjitsu) in episode 141 of the Naruto: Shippūden anime. Madara Uchiha awakened his Eternal Mangekyo Sharingan by taking his brothers' eyes and implanting them in his own.
