An Australian senator has called on her government to boycott an international summit in Sri Lanka after she and a New Zealand lawmaker were detained by authorities in the South Asian island nation over the weekend.

Greens party Sen. Lee Rhiannon says she and New Zealand lawmaker Jan Logie had been preparing to hold a press conference on human rights issues in Colombo on Sunday morning when immigration officials seized their passports and took them back to their hotels for questioning.

Rhiannon told the Australian Broadcasting Corp. that Australian Prime Minister Tony Abbott should boycott the summit of British Commonwealth leaders in Sri Lanka this week.

The prime ministers of India and Canada have already pulled out of the summit due to human rights concerns.
