"RT en Espanol correspondent Nicolas Sanchez was injured during the coverage of the protest in Quito, when Ecuadorian police arrived at the event and began dispersing the demonstrators using tear gas ... An explosive cartridge fell next to the correspondent, he was stunned", the statement said.
The operator who worked with Sanchez was also injured, it added.
Ecuadorians, who are dissatisfied with the government's economic reforms, began protests on Thursday.
Ecuadorian President Lenin Moreno has declared a state of emergency in connection with the protests.
Ecuador's transport services conducted a two-day strike that literally paralyzed the country.
Despite massive protests, Moreno said the authorities would not reconsider the decision to abolish gas subsidies, which had been agreed with the International Monetary Fund.
Ecuador's economy is suffering from a heavy debt burden of about $3.6 billion, which grew under previous leadership. Moreno has been adamant about slashing the debt to about $1 billion by 2020.
Last week, the government announced it would be leaving the Organization of the Petroleum Exporting Countries in order to increase crude oil production to raise more income.
