April 15 (Reuters) - Indian shares opened higher on Wednesday, tracking other Asian peers, after oil prices dropped below $100 a barrel on rising expectations for a resumption of U.S.-Iran peace negotiations.

The Nifty 50 rose 1.35% to 24,163.80 and the Sensex added 1.48% to 77,981.10 as of 9:15 a.m. IST.

All 16 major sectors advanced at the open. The broader small-caps and mid-caps gained 1.8% each.

Other Asian markets gained 1.7%, while Wall Street equities advanced overnight after U.S. President Donald Trump said talks with Iran could resume in Pakistan over the next two days, after breaking down last weekend. [MKTS/GLOB]

Pakistani and Iranian officials also said negotiations could restart, sending Brent crude prices lower and bolstering expectations of a de-escalation in the war. [O/R]
