Police have removed 200 fake explosive devices from Bahrain's roads since the start of the year, officials have revealed.
Sixteen people have been injured as a result, including many policemen, said Special Security Forces specialised operation section head Lieutenant-Colonel Ali Al Zabi.
He said saboteurs continued to place such devices on major highways and warned the public not to go near suspicious objects.
"Our team (the bomb disposal unit in the Interior Ministry's anti-terror unit) dealt with 200 cases since January 2012," Lt-Col Al Zabi told the ministry's Al Amn radio station.
"It resulted in the death of a youth and injury to 16 individuals, with major injuries that led to deformities and permanent disabilities."
Ahmed Al Dhufairi, 18, was fatally injured in an explosion near Roundabout 18 in Hamad Town last April, as he tried to remove burning tyres from a road - triggering an explosive device hidden between the tyres.
He suffered second and third degree burns to his face, neck, hands and legs and was treated at BDF Hospital and Salmaniya Medical Complex before being transferred to Al Hussein Medical City in Jordan, where he died on June 8.
Lt Col Al Zabi warned the public not to go near any suspicious objects, some of which may have to be defused by bomb disposal robots, and immediately call 999.
"People should maintain a distance between them and any strange object," he said.
"We also urge citizens and residents not to gather at the location and allow the teams to do its job."
Lt Col Al Zabi said police were using latest technology to remove fake explosive devices and suspicious objects placed on the roads by saboteurs and forensically analyse them.
The ministry's latest weekly security report, aired on Bahrain Television, showed two homemade explosives had been detonated. No casualties were reported.
It stated 136 Molotov cocktails, gas cylinders and other objects had also been found in Bilad Al Qadeem.
Police videos also showed vandals in Bani Jamra and Duraz setting tyres on fire and ambushing policemen, who had arrived to clear the debris, with firebombs.
The GDN reported last month that police in Sitra and A'ali seized more than 560 Molotov cocktails, 74 tyres and large quantities of iron rods, gas cylinders and other materials used in rioting.
In June, the ministry said 7,849 Molotov cocktails had been seized since the beginning of the year during raids in several areas.
Do you think the issue of road bombs signals that revolt in Bahrain is regaining popular momentum or is it just a sign of ongoing Shia resentment?
