Rubio says Iran deal still possible Monday

US Secretary of State Marco Rubio said Monday that a deal to end the war with Iran could materialise "today", adding that ‘Israel’ had the right to defend itself against attack.

"We thought we might have some news last night, maybe today, I wouldn't read too much into it," Rubio said in New Delhi, referring to the potential agreement.

"Israel always has a right to protect itself... if Hezbollah is going to launch missiles or launches missiles at them, Israel has every right to respond to that," he told reporters as he departed the Indian capital, where he has been on an official visit.
