Missing entries

• 1993 data is missing
• nkill data is missing for 12,527 entries out of 209,706, i.e., ~6%. It's especially high for the period of 1979-1986, for years 1982-1983 it reaches 31%. Therefore, the number of victims for this period is undervalued
• Latitude and longitude coordinates were added manually for 4,691 entries, based on country data
