"The incident was an act of sabotage and a dangerous act of terrorism aimed at harming the higher interests of the nation and the safety of the people," the ministry said on its website.
Bahraini authorities said they had brought under control the fire at the oil pipeline.
State-run Bahrain Petroleum Company (Bapco) closed the flow of oil to the stricken pipeline, the civil defence said in a statement earlier on Saturday.
Residents close to the incident near Buri village, some 15 kilometres from the capital Manama, were being evacuated to a safe shelter, the statement added.
Saudi Arabia's energy ministry said pumping to Bahrain had been suspended and the kingdom was stepping up security precautions at its own facilities.
Bahrain relies on the Abu Safa oilfield for the majority of its oil. It shares the field with Saudi Arabia. Oil to Bahrain is transported via the 55 km A-B pipeline which has a capacity of 230,000 barrels per day (bpd).
A new 350,000-barrels per day oil pipeline between the two countries will be completed next year and will serve the planned expansion of Bahrain's refinery capacity.
Arabian Light crude oil will flow from Saudi Aramco's Abqaiq plant via the 115-km new pipeline, 73 km of which will run overland and the rest under the Gulf.
Emergency and rescue workers are seen blocking the road leading to a fire in at oil pipeline in Buri village south of Manama, Bahrain.
Bahrain said an explosion which caused a fire at its main oil pipeline on Friday was caused by "terrorist" sabotage.
