Paris/Quetta, Apr. 5 : The United Nations (UN) has expressed satisfaction over the release of John Solecki, over two months after he was abducted by the Balochistan Liberation United Front (BLUF).

"I''m very pleased that John Solecki has been released. I''m very happy," UN Secretary General Ban Ki Moon said.

Moon also appreciated Pakistan President Asif Ali Zardari and Afghan head of state Hamid Karzai for their efforts to ensure the safe return of Solecki.

The United Nations High Commission for Refugees (UNHCR) provincial head John Solecki, was left abandoned by the abductors in a village in Mastung, in Southern Quetta. However, it is still not clear as to what prompted the rebellious group to free Solecki suddenly.

Soon after his release, a BLUF spokesman said that Solecki was released on humanitarian grounds.

Moon, who is in Paris for talks with French Foreign Minister Bernard Kouchner, also urged for an immediate release of UN's special envoy to Niger, who went missing with his assistant Louis Guay in December 2008.

"I sincerely hope that the captors, whoever they may be, should immediately, without any condition, release him as soon as possible," The News quoted Moon, as saying.

Immediately after his release Solecki was admitted to the Combined Military Hospital (CMH) in Quetta for medical treatment.

Pakistan's Interior Advisor Rehman Malik said Solecki is fine and healthy, and would soon be released from the hospital. (ANI)
