Muhammad Saif-ur-Rehman Khan has denied handling explosives
A Pakistani student arrested at the US embassy in Chile after triggering a bomb detector has been charged with illegal possession of explosives.
The man, identified by the US state department as Muhammad Saif-ur-Rehman Khan, had been detained under anti-terrorism laws since the incident.
Police said traces of the explosive, Tetryl, had been found on documents and a mobile phone in his possession.
Mr Khan denies any wrongdoing and has been freed pending an investigation.
He earlier blamed the US for his detention after being taken into custody last Monday.
"I have nothing to do with bombs. I have nothing to do with terrorists. I don't have a beard," he told reporters on Tuesday.
"They [the United States] just want to cover up their shame and guilt for what they have done or are doing in Iraq and Afghanistan."
The judge on Saturday did not invoke anti-terrorism laws when announcing the charges.
Mr Khan, a student who had been in Santiago for four months, had been invited to the embassy to be told his US visa had been revoked.
His arrest came days after a Pakistani-born American was charged with an attempted bombing in New York's Times Square.
But US officials said they were not aware of any possible link between the two men, and US ambassador Paul Simon said he did not think Mr Khan had been trying to attack the embassy.
Tetryl is a compound used as a booster to help detonate explosives.
