Soleimani's killing sharply escalated tensions between the U.S. and Iran and stoked fears of a military conflict. Iranian leaders vowed revenge, while U.S. officials said they would preemptively attack any Iran-backed paramilitary groups in Iraq that they perceived as a threat. Many in the international community reacted with concern and issued statements or declarations urging restraint and diplomacy. Five days after the airstrike, Iran launched a series of missile attacks on U.S. forces based in Iraq, the first direct engagement between Iran and the U.S. since the naval battle precipitating the Vincennes incident on 3 July 1988. Following the shootdown of Ukraine International Airlines Flight 752 amidst the escalation, leaders from both countries seemed reluctant to further escalate the crisis.
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".

More InfoIndia has hosted or co-hosted several international sporting events: the 1951 and 1982 Asian Games; the 1987, 1996, and 2011 Cricket World Cup tournaments; the 2003 Afro-Asian Games; the 2006 ICC Champions Trophy; the 2010 Hockey World Cup; the 2010 Commonwealth Games; and the 2017 FIFA U-17 World Cup. Major international sporting events held annually in India include the Chennai Open, the Mumbai Marathon, the Delhi Half Marathon, and the Indian Masters. The first Formula 1 Indian Grand Prix featured in late 2011 but has been discontinued from the F1 season calendar since 2014. India has traditionally been the dominant country at the South Asian Games. An example of this dominance is the basketball competition where the Indian team won three out of four tournaments to date.
More InfoIn the last 50 years, fashions have changed a great deal in India. Increasingly, in urban settings in northern India, the sari is no longer the apparel of everyday wear, transformed instead into one for formal occasions. The traditional shalwar kameez is rarely worn by younger women, who favour churidars or jeans. The kurtas worn by young men usually fall to the shins and are seldom plain. In white-collar office settings, ubiquitous air conditioning allows men to wear sports jackets year-round. For weddings and formal occasions, men in the middle- and upper classes often wear bandgala, or short Nehru jackets, with pants, with the groom and his groomsmen sporting sherwanis and churidars. The dhoti, the once universal garment of Hindu India, the wearing of which in the homespun and handwoven form of khadi allowed Gandhi to bring Indian nationalism to the millions,is seldom seen in the cities, reduced now, with brocaded border, to the liturgical vestments of Hindu priests.
More InfoIn 1881, Charles Fritts created the first commercial solar panel, which was reported by Fritts as "continuous, constant and of considerable force not only by exposure to sunlight but also to dim, diffused daylight." However, these solar panels were very inefficient, especially compared to coal-fired power plants. In 1939, Russell Ohl created the solar cell design that is used in many modern solar panels. He patented his design in 1941. In 1954, this design was first used by Bell Labs to create the first commercially viable silicon solar cell. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
