US President repeated anti-Iran threats as his administration have been going back and forth with Tehran in the last month amid growing tensions in the region.

Iran Press/America: "We'll see what happens with Iran. Iran has to be very, very careful," Donald Trump told reporters at the White House on Friday, Iran Press reported citing White House statement 

Earlier this week, Trump responded to Iran’s announcement by warning it on Twitter, “Be careful with the threats, Iran. They can come back to bite you like nobody has been bitten before!"

The warning came after Iran increased the level of its low-enriched uranium production to over 300 kilograms.

Repeating anti-Iran threats, Trump and his administration have constantly said that they will negotiate with Iran with “no preconditions.”

The Leader of Islamic Revolution Ayatollah Seyyed Ali Khamenei, described the US offer to negotiate with Tehran, a 'trick' to disarm this nation.

"Washington’s offer is, in fact, meant to strip Iran of its weapons and eliminate its elements of power,” Ayatollah Khamenei addressed a meeting with senior Judiciary officials at Tehran’s Hussayniyah of Imam Khomeini on July 26.

"Negotiations are their way of deceiving into what they want. You hold the gun and the other side doesn’t dare approach you; so they say drop your gun so that I can do any harms to you. This is what they mean by negotiations," he noted. 101/213
