Dubai: Bahraini security forces have arrested four people suspected of attacking a police checkpoint with petrol bombs south of Manama at the weekend, the interior ministry said.

“Four of the terrorists who attacked police checkpoint on Sunday evening with petrol bombs have been arrested,” the ministry said late Monday.

It said the attack took place in the district of Jari Al Shaikh, south of the capital, adding the identity of others suspected of being involved was being probed.

The alleged attack came amid frequent clashes between security forces and protesters in villages.

The archipelago was rocked by a month-long uprising in 2011 which was put down with the help of Gulf troops led by neighbouring Saudi Arabia.

A total of 80 people have been killed in Bahrain since the protests erupted, according to the International Federation for Human Rights.

Strategically located just across the Gulf from Iran, Bahrain is home base to the US Navy’s Fifth Fleet and is also a major offshore financial and services centre for its Arab neighbours in the Gulf.
