Parents Of Detained Journalist Peter Greste Say They're At 'Breaking Point'

The parents of Peter Greste, one of the Al Jazeera journalists being held by Egyptian authorities, said at a press conference Thursday that their son's arrest has brought them past their "breaking point."

Greste was detained along with three other journalists working for Al Jazeera at the end of December. The Ministry of the Interior accused them of conspiring with the Muslim Brotherhood and "broadcasting false news." Al Jazeera and journalists from other news organizations have condemned the arrests. One of Greste's colleagues was later released, while Greste and his two other colleagues have been in Tora prison in Cairo and are being tried on charges related to terrorism.

"With such scant and difficult communications, it is just taking us literally to breaking point, which we reached a couple of days ago," Greste's father Juris told reporters in Brisbane on Wednesday.

Greste's parents said they have not spoken to their son since last Friday. Peter Greste spoke out against his arrest and the detention of his colleagues in letters smuggled out of prison. He wrote that he could no longer stay silent, though he feared the consequences of writing the letters.

"It is unbecoming of a great nation like Egypt," Juris Greste told reporters about his son's arrest. "It's demeaning of any community which even pretends to be democratic and fair."
