Lol, they said "The Tehran Times",
Not "Tehran Times"
Give it a rest, mate. Using definite article "THE" before the names of newspapers is basic (English) grammar. You yourself could have easily verified which "Tehran Times" established "Mehr News Agency", from their official website:
"In 2002, Tehran Times decided to establish a news agency which later came to be known as the Mehr News Agency (MNA). Now, Tehran Times and MNA are run by a single management system with MNA staff triple that of TT. "
