Myanmar's ruling National League for Democracy (NLD) party has condemned the assassination of its legal adviser U Ko Ni, calling for arrest of the mastermind behind the plot, the NLD said on Monday.

Saddened by the assassination, the NLD said the death of U Ko Ni is an irreparable loss to the party and State Counselor Aung San Suu Kyi, denouncing the assassination plot as a terrorist act that opposes the path of the NLD.

The party led by Suu Kyi called for non-extreme acts in response to the incident and staying in peace to cope with it, while continuing implementation of the party's political path.

The NLD's legal adviser was gunned down at the Yangon international Airport Sunday afternoon upon his arrival back from Indonesia.

The gunman also killed a taxi driver who had tried to capture him before he was arrested by the police and bystanders.

U Ko Ni was shot in the head at point-blank range by the gunman at the airport's taxi stand near terminal-1.

Initial investigation revealed that the attacker U Kyi Lin was a resident in Mandalay region.

U Ko Ni was a prominent practicing lawyer and consulted various clients for the past four decades. He established the Laurel Law Firm in 1995.

U Ko Ni's funeral will be held on Monday, according to the 88-Generation Peace and Open Society.
