All the prisoners escaped from the main jail in the capital of Central African Republic on Monday, a senior security source said, in a city where at least 30 people have been killed in three days of violence.

“There is no one in the prison. They have all left,” according to a senior gendarmerie source, referring to the Ngaraba jail. He gave no details of the escape.

Meanwhile, the country’s interim president, Catherine Samba-Panza, left the United Nations General Assembly in New York on Monday to return home due to the worst violence in the capital of her country this year, two Western diplomats said.

Around 30 people have been killed and over 100 more injured in three days of intercommunal clashes in Bangui, a city secured by U.N. and French peacekeepers. The violence has sparked fears that Samba-Panza could be overthrown.

“She left (New York) to go back to Central Africa because of the security situation,” a diplomat told Reuters.

In New York, U.N. Secretary-General Ban Ki-moon and the U.N. Security Council condemned the violence.

“(Ban) strongly condemns all acts of violence and calls for an immediate end to the unacceptable violence and retaliatory attacks,” his press office said. “He urges the Central African Republic’s Transitional Authority to do everything within its means to prevent further violence.”

The Security Council warned in a statement that it remains prepared to blacklist individuals and entities that undermine peace and stability in the country.
