Last month, the Trump administration exempted India from imposition of certain sanctions for the development of the strategically-located Chabahar Port in Iran, along with the construction of the railway line connecting it with Afghanistan.
MEA said India condemned the "despicable terror" attack. At least two people were killed and several wounded outside police headquarters in the port city of Chabahar when a suicide bomber blew up a car.
The port in the Sistan-Balochistan province on the energy-rich nations southern coast is easily accessible from India's western coast and is increasingly seen as a counter to Pakistan's Gwadar Port, which is being developed with Chinese investment.
China plans to push for greater maritime capabilities along strategic sea routes and if the deal to acquire Pakistani military base goes through, the new facility will come up at Jiwani close to Iran border in the Gulf of Oman only 85km from China's Gwadar port in Pakistan.
