Movement of tanks and armored vehicles can be seen, according to the news agency. The government forces are reported attacking the headquarters of the opposition Socialist Party without Borders.
Earlier in the day, the Chadian Communications Ministry said that several people have died as a result of an attack on buildings of the Chadian National Directorate of Security, with the country's authorities blaming members of an opposition party for the incident.
Chad's opposition party, the Socialist Party without Borders, has allegedly called for the assassination of the head of the Chadian Supreme Court, but an attempt has never been committed, the ministry said, adding that the secretary of the party, who is responsible for its funding, had been detained.
"Despite this fact, the situation took a dramatic turn due to the deliberate attack by his [the secretary's] accomplices led by elements of the Socialist Party without Borders and its president, Yaya Dillo, on the buildings of the country's national security directorate, which resulted in several deaths," the ministry said on social media.
The situation in the country is currently under control, with all those involved in the attack detained or put on the wanted list, the statement read.
