May 18 (Reuters) - Indian shares opened lower and the rupee slid to a record low on Monday, as oil prices jumped after a drone attack on a nuclear power plant in the United Arab Emirates intensified tensions in the Middle East. 

The mood was further dampened after U.S. President Donald Trump warned that "the clock is ticking" for Iran, as efforts to end the Middle East conflict appeared to have stalled.

The Nifty 50 fell 1.1% to 23,391.9 and the BSE Sensex lost 1.16% to 74,374.04 as of 9:16 a.m. IST.

All 16 major sectors declined. The broader small-caps and mid-caps lost 1.5% and 1.2%, respectively.

The rupee weakened to an all-time low as higher oil prices sent global bond yields soaring.  

Brent crude rose to $112 a barrel, a two-week high. Other Asian markets fell 0.8%.
