The discovery of Okechukwu Okoye's mutilated body has sparked outrage, the BBC's Ishaq Khalid reports from Abuja.
请问此句是不是为：The BBC's Ishaq Khalid reports from Abuja that the discovery of Okechukwu Okoye's mutilated body has sparked outrage.的变化形式？
以上用逗号隔开的写法是不是规范？
The BBC's Ishaq Khalid reports from Abuja that the discovery of Okechukwu Okoye's mutilated body has sparked outrage. 这是普通的句子，that从句为间接引语，以宾语从句的形式出现。reports为引述分句，作为主句。
The discovery of Okechukwu Okoye's mutilated body has sparked outrage, the BBC's Ishaq Khalid reports from Abuja. 间接引语目前以主句的形式出现，引述分句则以插入语分句的形式出现，逗号的用法是需要的，由于引述分句为插入语。这种结构语法上称为自由间接引语。
