  During the partition of India, around five hundred thousand Hindu and Sikh refugees, mainly from West Punjab fled to Delhi, while around three hundred thousand Muslim residents of the city migrated to Pakistan. Ethnic Punjabis are believed to account for at least 40% of Delhi's total population and are predominantly Hindi -speaking Punjabi Hindus. Migration to Delhi from the rest of India continues (as of 2013), contributing more to the rise of Delhi's population than the birth rate, which is declining.
  
  The States Reorganisation Act, 1956 created the Union Territory of Delhi from its predecessor, the Chief Commissioner's Province of Delhi. The Constitution (Sixty-ninth Amendment) Act, 1991 declared the Union Territory of Delhi to be formally known as the National Capital Territory of Delhi. The Act gave Delhi its legislative assembly along Civil lines, though with limited powers.
  
  Delhi was the primary site in the nationwide anti-Sikh pogroms of 1984, which resulted in the death of around 2,800 people in the city according to government figures, though independent estimates of the number of people killed tend to be higher. The riots were set off by the assassination of Indira Gandhi —the Prime Minister of India at the time—by her Sikh bodyguards.
  
  In 2001, the Parliament of India building in New Delhi was attacked by armed militants, killing six security personnel. India suspected Pakistan-based Jihadist militant groups were behind the attack, which caused a major diplomatic crisis between the two countries. There were further terrorist attacks in Delhi in 2005 and 2008, resulting in a total of 92 deaths. In 2020, Delhi witnessed worst communal violence in decades. The riots, caused mainly by Hindu mobs attacking Muslims, 53 people were killed, two-thirds were Muslims, and the rest Hindus.
