U.S. President Barack Obama said on Friday the United States would keep trying in the coming months to reach a nuclear deal with Iran and said Washington would increase aid to $1 billion annually to Middle East ally Jordan.

Obama, speaking after a visit with Jordan's King Abdullah at the White House, said it was unclear whether Tehran would seize its chance for a deal in nuclear talks with western powers.

"I briefed His Majesty about our negotiations with Iran, and indicated to him that we would prefer no deal to a bad deal, but that we continue to hold out the possibility that we can eliminate the risk of Iran obtaining a nuclear weapon," Obama told reporters.

"Whether Iran seizes this opportunity or not is something we have not yet been able to determine, but we will keep on trying over the next several months and will keep Jordan apprised."

Washington sees Jordan as a critical ally in the region, and Obama praised the country for hosting refugees displaced by the war in Syria.

He said the United States would provide an additional loan guarantee and more aid to Jordan "to reinforce the sort of political and economic reforms that have taken place inside of Jordan."

He said Jordan had been strong partner in trying to broker a peace deal between the Zionists and Palestinians.
