Pope Francis called on Sudan’s warring forces to lay down their arms on Sunday, expressing dismay about the ongoing fighting and worsening humanitarian situation in the African country.

“It’s sad that a month after the explosion of violence in Sudan, the situation continues to be grave,’ he told the faithful who’d gathered in St. Peter’s Square for his weekly appearance.

For over a month, the Sudanese army, led by Gen. Abdel Fattah Burhan, and the paramilitary Rapid Support Forces, commanded by Mohamed Hamdan Dagalo, have been locked in a violent power struggle that has killed more than 800 civilians, the Sudan Doctor’s Union said.

“Please, let’s not get used to conflicts and violence, and let’s not get used to war, please,” Pope Francis said during his appeal. The Pope’s call comes a day after the Sudanese army and the RSF agreed to a seven-day ceas-efire due to take effect Monday evening.

Since the conflict began, there have been numerous shorter cease-fire deals, and all have foundered.

According to a joint statement issued by the US and Saudi Arabia — the brokers of Saturday’s deal — the upcoming truce hopes to facilitate the “delivery of emergency humanitarian assistance and restoration of essential services.”

The cease-fire could be extended if both sides agree.

Unlike the previous cease-fires, the week-long truce will be backed up by a “US-Saudi and international-supported cease-fire monitoring mechanism,” the statement said. Few further details about the function or role of the mechanism were provided.
