US, Iran remain far from breakthrough as Iranian demands stall talks: Rubio

US Senator Marco Rubio has downplayed expectations of reaching a near-term agreement with Iran, stating that Washington and Tehran are not on the verge of a diplomatic breakthrough.

According to CBS, Rubio said that Iranian demands—described as "unacceptable"—have hindered progress in negotiations between the two sides.

Despite stalled talks, Rubio stressed that a diplomatic solution remains the preferred option for US President Donald Trump.
