Heavy fall in the Indian rupee value against the US dollar after global oil prices surged on supply concerns over the unrest in Iraq led the Indian currency to log its third straight weekly fall in an otherwise dull trading week.
Sustained dollar demand from importers and some weakness in local equities also weighed on the rupee, a forex dealer said.
Crude prices logged a nine-month high after militants closed in on Iraq's capital Baghdad, fuelling fears over supplies from the crude producer.

Later, it moved in a narrow range till Thursday on alternate bouts of demand and supply before succumbing to heavy dollar demand from importers on Friday to register a low of 59.80. It finished the week at 59.77, revealing a fall of 60 paise, or 1.01 per cent.
It has plunged by 125 paise, or 2.14 per cent.
On Friday, it lost 52 paise -- its biggest drop since January 24, 2014 -- when it had dropped by 73 paise.
The benchmark S&P BSE Sensex closed down by 168.29 points, or 0.66 per cent, while FIIs injected USD 640.68 million in the first four days of the week, as per Sebi data.
"Suspected intervention by the central bank was seen in the afternoon and demand for the greenback from importers put pressure on rupee," said Kiran Kumar Kavikondala, Director & CEO, WealthRays Securities.
Pramit Brahmbhatt, Veracity Group CEO said, "Rupee depreciated during the week taking cues from local equities which gave up almost all the gains posted during the week.
"In spite of FIIs buying shares worth Rs 1,557 crore till Thursday, indices closed on a weak note. On Monday, the trading range for the Spot USD/INR pair is expected to be within 59.30 to 60.30."
