May 18 (Reuters) - The Australian share benchmark hit its lowest level in more than a month on Monday, bogged down by heavyweight commodity-linked stocks, while a surge in crude prices fanned inflationary worries.

Market uncertainty loomed after efforts to end the U.S.-Israeli war with Iran appeared to have stalled, while U.S. President Donald Trump warned that the "clock is ticking" for Iran if its leaders do not act quickly.

Oil prices touched a two-week peak on the day after a nuclear power plant in the United Arab Emirates came under attack, bringing inflation fears back to focus for Australia, which is already grappling with a jump in consumer prices. O/R
