SOFIA, June 8 (Xinhua) -- Bulgarian authorities have detained a 16-year-old boy suspected of terrorism, and seized many bombs made by him, an official said here on Saturday.
During the operation, which was held on Wednesday in Plovdiv after the authorities were alerted by the teen's relatives, many improvised explosive devices ready for use and under construction were found in two rooms used by the boy, Deputy Prosecutor General Ivan Geshev said at a press conference.
The largest of the bombs was under construction and contained 14.5 kg of explosive, Geshev added.
Such an explosive has been used in some attacks in Belgium and France, and also in the terrorist act at Burgas Airport in Bulgaria in 2012, Geshev said.
Authorities also found many instructions for preparing explosives and bombs, as well as a flag of Islamic State, according to Geshev.
The investigation has established that the teen was recruited by the Islamic State via internet, Geshev said.
The bombs were made of publicly available ingredients, and the boy said he had made the bombs within seven or eight days, Geshev added.
"We are talking about a single case. This is an individual case of radicalizing a super intelligent child of a good family," Geshev said.
The investigation is ongoing.
In 2012, a Lebanese-born terrorist blew himself up near an Israeli-packed tourist bus at the Burgas airport, killing five tourists, their Bulgarian driver and himself.
