- Pro-democracy activists kick off three days of rallies at Hong Kong's airport.
- The weeks of demonstrations pose the biggest threat to Beijing's authority since Hong Kong's handover from the British in 1997.
- Several countries have upgraded their travel warnings for Hong Kong, with US this week urging its citizens to "exercise increased caution."
Pro-democracy activists kicked off three days of rallies at Hong Kong's airport on Friday, hoping to win international support from arriving passengers as the protests that have rocked the city enter a third month.
The rallies, promoted on social media with a mock boarding pass reading "HK to freedom" and "warm pick-up to guests to HK", will be the second time protesters have brought their message to the international travel hub.
The gatherings, expected to run over three days, have not been authorised, but the last demonstration at the airport passed off peacefully without causing flight disruptions.
The protests that began in opposition to a plan to allow extradition to mainland China have morphed into a broader movement seeking to reverse a slide in freedoms in the city.
Demonstrators have staged protests throughout Hong Kong and held rallies for families, older people, lawyers and civil servants, in a bid to show their demands have broad and enduring support.
