April 30 (Reuters) - India cut export duties on diesel and aviation turbine fuel on Thursday and left duties on domestic consumption of petrol and diesel unchanged, its government said in a statement.

In a notification, the government said the export duty on diesel was cut to 23 rupees ($0.2424) per litre from an earlier 55.5 rupees. The export duty on aviation turbine fuel was cut to 33 rupees from 42 rupees earlier.

The duty rates on petrol and diesel for domestic consumption remained unchanged, while those on the export of petrol continued to remain nil.

India, the world's third-biggest oil importer and consumer, has been hit by rising oil prices triggered by the closure of the Strait of Hormuz after the U.S.-Israeli war on Iran.

India's crude import prices rose to $120 per barrel earlier this month, denting the margins of retailers on the sale of gasoline and gasoil.

Indian refiners have not raised pump prices ?of gasoline and gasoil in four years to shield consumers, despite volatility in global markets.

Separately, to control a rise in airfares, the government has also capped a monthly increase in aviation turbine ?fuel prices for domestic airlines at 25% in April. Jet fuel accounts for up to 40% of an airline's expenses.
