The wife and children of slain political analyst Kem Ley have landed safely in Melbourne, Australia as refugees.

Bou Rachana and her five young sons arrived in Australia on Saturday, according to an official Twitter account established in memory of Ley, with confirmation from Victorian Member of Parliament Hong Lim.

“They arrived safely on Saturday,” Lim said late Monday night in a message. “It was horrendous drama at BKK [Bangkok] airport. We thought we lost them …The community is celebrating and welcoming at the temple this Saturday.”

Ley, a prominent government critic, was gunned down in broad daylight in July 2016, just days after he commented on a damning Global Witness report about Prime Minister Hun Sen’s family’s illicit business links.

Shortly after Ley’s funeral, which amassed tens of thousands of mourners, Rachana fled with her children to Thailand, where she claimed refugee status. Rachana was pregnant with Ley’s fifth son when he was killed, and gave birth to Kem Ley Virak in October that year.

While the shooter, Oeut Ang, has been sentenced to life in prison, many observers - among them opposition movement leader Sam Rainsy - alleged Ang was merely a pawn in a politically motivated assassination orchestrated by Prime Minister Hun Sen’s government.

Last week in Australia, Rainsy commented on the slow process Rachana and her sons faced, suggesting Australia’s controversial and expensive refugee deal with Cambodia kept the Australian government tight-lipped on human rights abuses and made it reluctant to accept refugees itself.

“It would be very embarrassing to accept refugees from Cambodia when you send refugees to Cambodia,” he said at the time.

The Post reported in July last year that the Ley family’s claim for asylum had been accepted in Australia, but visas had yet to be issued as they waited in Thailand for more than six months.
