“The blast in the village of Sanabis slightly injured a female passerby,” the ministry tweeted.
The authorities have since launched an investigation into the incident.
Thursday’s blast was not the first such incident of its kind.
On Feb. 14, a man and his wife were slightly injured by a “terrorist” bombing in eastern Bahrain’s Sirta area. Ten days earlier, a bomb blast shook Bahraini capital Manama without causing casualties.
On Tuesday, the Interior Ministry said the authorities had arrested 20 people suspected of involvement in “terrorist” activity, including eight who had allegedly received military training in Iran and Iraq.
Bahrain was rocked by revolt in 2011, when pro-democracy protests erupted in the tiny Gulf state as part of the "Arab Spring" uprisings.
The country’s Sunni-led government blames Al-Wefaq, Bahrain’s largest opposition movement, for the upheaval, accusing the Shia party of pursuing an “Iranian agenda”.
