Controversial Australian Senator Pauline Hanson has backed the Sentinelese tribe's "immigration policy" after the group reportedly killed an American missionary looking to convert the group.
John Chau, a devout Christian, was believed to be shot to death with arrows after travelling to the North Sentinel Island to covert its local tribe to Christianity.

International advocacy groups have called for the tribe to be left alone, and they have found an unlikely ally in Ms Hanson.
The Senator has gone as far as to ask the Australian Senate if they will support the Sentinelese people's "zero-gross immigration policy".
On Tuesday she asked the Senate acknowledge that the tribe are likely the "last pre-Neolithic tribe in the world and possess a unique culture a way of life that should be cherished and protected".
"Even small levels of migration would have a devastating and irreversible effect on the beautiful and unique culture and way of life of the Sentinelese people," the motion says.
But her endeavour didn't gain support by her fellow Senators, with Senator Nick McKim saying Ms Hanson was exploiting the tribe for political points, reports news.com.au.
Ms Hanson is known for her strong and populist immigration views, including in October introducing a motion for the Senate to acknowledge "the deplorable rise of anti-white racism and attacks on Western civilisation" and that it "is okay to be white".
Stephen Corry from Survival International said Mr Chau's death shouldn't have happened.
"The Indian authorities should have been enforcing the protection of the Sentinelese and their island for the safety of both the tribe and outsiders."
Authorities issued a statement on Monday reiterating the island is off limits for several reasons, including concerns about the immunity of the tribe to common illnesses.
