On 28 September 1961, secessionist army units launched a coup in Damascus, declaring Syria's secession from the UAR. In response, pro-union army units in northern Syria revolted and pro-Nasser protests occurred in major Syrian cities. Nasser sent Egyptian special forces to Latakia to bolster his allies, but withdrew them two days later, citing a refusal to allow inter-Arab fighting. Addressing the UAR's breakup on 5 October, Nasser accepted personal responsibility and declared that Egypt would recognize an elected Syrian government. He privately blamed interference by hostile Arab governments. According to Heikal, Nasser suffered something resembling a nervous breakdown after the dissolution of the union; he began to smoke more heavily and his health began to deteriorate.
