DUBAI — Iran will never hold talks with America, the country's Supreme Leader Ayatollah Ali Khamenei said on state television Tuesday morning, effectively killing chances for a rapprochement some had anticipated between leaders of both countries during the United Nations General Assembly (UNGA) meetings taking place this week and next. "Iranian officials will never talk to America .... this is part of their (U.S.) policy to put pressure on Iran ... their policy of maximum pressure will fail," Khamenei said. Khamenei's words come ahead of the high level meetings at the UNGA scheduled for next week, and amid fresh acrimony between Washington and Tehran following major attacks on Saudi oil infrastructure that U.S. officials have blamed on Iran. The attacks on Saudi Aramco's massive Abqaiq and Khurais plants, which was claimed by Yemen's Houthi rebels, forced the state oil giant to shut down half of its production, sending oil prices up by double digits. Pompeo on Sunday took to Twitter to squarely blame the Iranians, who rejected his charge as "meaningless" and "pointless." President Donald Trump, meanwhile, has appeared reticent to draw as decisive a conclusion, saying on Monday that he's in no rush to respond to the attacks.

"It's certainly looking that way at this point," Trump said, speaking on whether Iran was responsible for the attacks. "I don't want war with anybody but we are prepared more than anybody ... We have a lot of options but we are not looking at options right now." "That was a very large attack and it could be met with an attack many, many times larger very easily by our country, but we are going to find out who definitively did it first," he said. A Saudi-led military coalition said the attack was carried out by "Iranian weapons" and did not originate from Yemen.
