Iranian Foreign Ministry spokesman Saeed Khatibzadeh in a message referred to US threatening to pull out of the talks, saying, "Iran is willing, but will not wait forever."
"US has already 'walked away' from JCPOA. We must make sure it won't happen again," Khatibzadeh wrote in his Twitter account on Tuesday.
"Everyone has its own plan B, though US' has proven hollow," he added.
"Blusters & bluffs have/will not work. Decisions do. A deal is at hand, if WH makes its mind," he noted.
"Iran is willing, but will not wait forever," he noted.
