Bahrain hit back at US expressions of concern over the Gulf kingdom's treatment of opposition figures on Wednesday, saying all its actions followed due legal process.

The State Department on Tuesday said the arrest of Ibrahim Sharif, prosecution of Majeed Milad and reports that a case against Ali Salman, head of Bahrain's main opposition group, had been reopened, "raise serious concerns about restrictions on freedom of expression". 

In response, Bahrain's Foreign Ministry said in a statement the individuals were detained on the basis of criminal acts not political expression. "The government of Bahrain will not tolerate incitement to violence, and it is the government's duty to protect citizens, residents and visitors alike," it said.

Bahrain, which hosts the US Fifth Fleet, has experienced sporadic protests since 2011.

The official BNA news agency said on Monday Rajab had been freed from a six-month jail term imposed in May for insulting the authorities. It cited health reasons for the release.

Last year Bahrain denied entry to a US congressman seeking to meet opposition figures, and expelled US Assistant Secretary of State for Democracy, Human Rights and Labour Tom Malinowski for meeting Ali Salman.

Meanwhile, a man was killed trying to plant a bomb targeting police in a village near the Bahraini capital, the interior ministry said on Wednesday.

The ministry, on its Twitter account, said the failed attack took place in the village of Ekr but it did not identify the man killed.

Security forces cordoned off the area, residents said.
