(CNN)The Ethiopian government has dismissed calls for a ceasefire from Tigrayan fighters in the north of the country, saying the olive branches it previously offered them have been rejected many times.

The leader of Ethiopia's northern Tigray region had announced a withdrawal of rebel forces from neighboring areas in the country on Sunday, a move that raised hopes of a ceasefire after 13 months of war.
But Prime Minister Abiy Ahmed's spokesperson Billene Seyoum on Tuesday cast doubt on the motives of the Tigray People's Liberation Front. "The resolution of this phase is something that we're committed to in terms of ensuring that it's done in a peaceful way and through a political means. Nevertheless, any political solution will always be centered on justice, will be centered on accountability, and also in dialogue," Billene told reporters in Addis Ababa.
    Billene said that she could not say which parties would be engaging in the dialogue, adding that whether the TPLF's actions are "a strategic retreat or not, will inevitably reveal itself."
      Tigrayan forces and Ethiopia's federal government have been engaged in conflict since November 2020, when Ethiopian Prime Minister Abiy Ahmed ordered a military offensive in Tigray following lengthy disputes over the governance of the region.
      The fighting has left thousands dead, displaced more than 2 million people, fueled famine and given rise to a wave of atrocities.
      In a letter to UN Secretary-General António Guterres and UN Security Council President Abdou Abarry, dated Sunday and seen by CNN on Monday, Debretsion Gebremichael, the leader of Tigray's region, said he had "ordered those units that are outside the borders of Tigray to withdraw to the borders of Tigray with immediate effect."
        Having heard the call to withdraw from both the international community and the Ethiopian federal government, Debretsion said the TPLF trusted that "their bold act of withdrawal will be a decisive opening act for peace," adding he hopes to commence peace negotiations following the cessation of hostilities.
        Abiy has denied civilians were being harmed or that soldiers from neighboring Eritrea had joined the fight, but reports from international observers, human rights groups and CNN have uncovered multiple atrocities.
        In Sunday's letter, Debretsion asked the UN diplomats to give their "full backing to an immediate cessation of hostilities followed by negotiations," and called on the UN Security Council to "establish a mechanism to ensure the immediate and veritable cessation of all forms of hostilities" and "the total withdrawal of all external forces" in the region.
        The Tigrayan leader also requested the establishment of a no-fly zone for hostile aircraft over Tigray, with the exception of humanitarian and civil purposes, as well as the imposition of arms embargoes on Ethiopia and Eritrea.
        In the letter, Debretsion also expressed a deep disappointment that the international community -- including the United Nations -- did not find a way to ensure food supplies made it into the region over the course of the conflict.
        "We trust that you and the Security Council will redouble your efforts to ensure that the war crime of starvation is stopped, and aid provided," he said.
        In September, UN aid chief Martin Griffiths declared that swathes of the war-torn region were in the throes of a "man-made" famine and urged the Ethiopian government to facilitate access. The Ethiopian government has repeatedly rejected allegations that it is blocking aid.
        Responding to the letter on Tuesday, Billene said that the Ethiopian government was still committed to a peaceful resolution.
        She pushed back on the TPLF's narrative regarding the pullout from Afar and Amhara, criticizing the international community and media for "amplifying" their message.
        "I think Ethiopia and it's heroic forces do not need external validation," she said. "As Ethiopians know the sacrifices that have been paid, and the challenges that had been countered in order to gain the current status quo, as well as the setbacks the TPLF has encountered."
        TPLF spokesperson Getachew Reda said in a Monday tweet that by withdrawing: "We believe we have taken away wh
