Peru's ancient Inca citadel of Machu Picchu has been closed indefinitely due to security concerns amid ongoing anti-government protests, which have resulted in 46 deaths and 58 injuries nationwide. The protests are calling for the resignation of President Dina Boluarte, and the government has responded by declaring a state of emergency and deploying the military to the streets. The closure of Machu Picchu is likely to have a significant impact on the country's economy.
