The UN agency has been working for many years in the region with refugees
Kidnappers who seized a senior United Nations official in Pakistan have released a video of him appealing for his freedom.
John Solecki, who works for UN refugee agency UNHCR, was taken from his vehicle in Quetta on 2 February by attackers who killed his driver.
In the video, the blindfolded official urges the UN to secure his release.
Last week a group called the Balochistan Liberation United Front (BLUF) said it was holding Mr Solecki.
The video was sent to local media outlets.
"I am not feeling well, I am sick and in trouble," Mr Solecki is seen saying. "Please help solve the problems soon so I can gain my release."
Quetta is capital of Balochistan, where insurgents have been fighting for more autonomy. BLUF is a previously unknown separatist group.
The Taleban are also active in the area, which borders Afghanistan.
The UNHCR has been working for years in Quetta with refugees from Afghanistan.
