A Mongolian opposition politician was beaten to death, the victim was a member of the Democratic Party (DP) and a governor of Sant Sum in central Mongolia, his party said in a statement.
The man was killed on Saturday, the party said.
Mongolia, which is three times the size of France but has a population of 3.5 million, is due to hold parliamentary elections on June 28.
Local media named the man as B. Bayanmunkh, while a statement by his party identified him as “BB”.
The DP said it was saddened that “a star of democracy… has lost his life at the hands of others”.
“At around 10:00 pm… B was killed by others during a meeting of five members of the MPP in the first round of parliamentary elections,” a party statement read, referring to the acronym of the ruling Mongolian People’s Party.
Violence during election campaigns is rare in the democratic country sandwiched between China and Russia, with all shades of the political spectrum represented in media and confrontational debate commonplace.
But critics say the country is experiencing a declining rule of law and a government seeking to curb criticism of its record on corruption.
