May 2 (UPI) -- An Iranian general said more fighting with the United States is "possible" after President Donald Trump rejected the most recent peace plan offered by Iran.

The United States and Iran are now in a fragile cease-fire.

"Evidence has shown that the United States is not committed to any promises or agreements," said Iranian Brig. Gen. Mohammad Jafar Asadi, spokesman for Iran's military headquarters, Iranian news agencies reported.

"Surprise measures are planned for the enemy, beyond their imagination," Asadi said.
