Three residential buildings in and around the Bahraini capital Manama were damaged by drone strikes and debris from an intercepted missile, the interior ministry said on Saturday.
Iran has carried out retaliatory strikes across the oil-rich Gulf following US and Israeli attacks, rattling a region long seen as a haven of peace and security in the region.
"Several residential buildings in Manama were targeted. Civil Defence continues with firefighting and rescue operations at the affected sites," the ministry said in a statement.
In another statement it reported "damage in three buildings in Manama and Muharraq as a result of drone attacks and falling debris from an intercepted missile".
Iran's Revolutionary Guards said they had targeted the US Fifth Fleet in Bahrain, after the Gulf state announced the American base had been hit by a missile attack.
The US embassy in Bahrain said it would close on Sunday, and the government announced all schools and universities would switch to long-distance learning until further notice following the Iranian attacks.
