WikiLeaks founder Julian Assange remains holed up at Ecuador's embassy in London as he seeks to avoid extradition to Sweden to face questioning on sexual assault charges.

Assange told Australian Broadcasting Corporation radio by phone Friday he fears that if extradited, he would be deported to the United States to face possible charges related to his website. Assange angered the U.S. when he began posting thousands of classified U.S. documents on his WikiLeaks website in 2010. Assange also accused officials in his native Australia of doing nothing to protect him. Canberra denies the accusation.

Assange said he believes U.S. officials have convened a grand jury to consider possible charges against him.

Ecuador's government is reviewing Assange's asylum request, but no timetable on a decision was given.

In the meantime, British police are standing by to arrest Assange on a bail violation if he steps outside the embassy.
