EDINBURGH, Scotland, July 1 (UPI) -- Links connecting three attempted car bombings in London and Glasgow, Scotland, are becoming "ever clearer," Britain's top counter-terrorism official said.
Deputy Assistant Commissioner Peter Clarke said he was "absolutely confident" investigators would uncover details of the attackers' methods and network, the BBC reported Sunday.
A Jeep containing gas cans was smashed into a terminal at Glasgow Airport Saturday, one day after two car bombs were found in London. Five suspects have been arrested in connection with the attacks and Britain is on its highest terror alert.
Police Paisley, Scotland, Sunday detonated a car parked at a hospital where a suspect in the Glasgow attack was being held. Authorities said the controlled detonation came after the vehicle was linked to the airport attack.
Authorities also cordoned off the area around the hospital.
Two of the suspects in custody are a 26-year-old man and 27-year-old woman who were arrested near Cheshire Saturday night. The man has been identified as Dr. Mohammed Asha, the BBC said.
"I'm confident -- absolutely confident -- that in the coming days and weeks we will be able to gain a thorough understanding of the methods used by the terrorists, of the way in which they planned their attacks, and of the network to which they belong," said Clarke.
Prime Minister Gordon Brown Sunday told the BBC it was "clear that we are dealing, in general terms, with people who are associated with al-Qaida."
Glasgow Airport was reopened Sunday afternoon.
