Bahrain has quashed an attempt to smuggle explosives and weapons into the country by boat , the Gulf state’s security chief said Monday.
“According to the investigations, which revealed plans to carry out terrorist acts, security deployment has been intensified,” Major-General Tariq al-Hassan said in comments published by the official news agency BNA, as carried by Reuters.
Security operations carried out Saturday and Sunday led to the discovery and seizure of plastic explosives and automatic rifles, as well as “50 Iranian-made hand bombs” and “295 commercial detonators on which was written ‘made in Syria.’” 
As well as the weaponry found onboard a boat intercepted as it was heading to the country, some of the weapons were discovered in a warehouse, the police chief said.
Security forces had also dismantled a car bomb east of Manama in the al-Houra area, seized a weapons and explosive store and arrested 13 people trying to flee the country by boat.
While the security chief did not specifically accuse Iran or members of the opposition of involvement, the “fugitives said that they were heading to Iran,” according to Hassan.
Homemade bombs  have become more frequent in Bahrain as a three-year anti-government opposition campaign continues. One blast on Friday injured two policemen, according to authorities.
