RAQQA, Syria — Hours after the expiration of a four-day truce between the Syrian government and Kurdish-led fighters Saturday, Syria's defense ministry announced the ceasefire had been extended by another 15 days.
The defense ministry said in a statement that the extension was in support of an operation by U.S. forces to transfer accused Islamic State militants who had been held in prisons in northeastern Syria to detention centers in Iraq.
The Kurdish-led Syrian Democratic Forces confirmed the ceasefire extension.
''Our forces affirm their commitment to the agreement and their dedication to respecting it, which contributes to de-escalation, the protection of civilians, and the creation of the necessary conditions for stability,'' the group said in a statement.
Over the past three weeks, there have been intense clashes between government forces and the SDF, in which the SDF lost large parts of the area they once controlled.
Earlier in the day, the Kurdish-led force called on the international community to prevent any escalation.
The end of the truce came as government forces have been sending reinforcements to Syria's northeast.
Syria's interim government signed an agreement last March with the SDF for it to hand over territory and to eventually merge its fighters with government forces. In early January, a new round of talks failed to make progress over the merger, leading to renewed fighting between the two sides.
