《美聯社》（AP）報導，一間位於伊朗首都德黑蘭（Tehran）北部、名為「Sina At’har」的醫療診所，30日晚間發生嚴重瓦斯氣爆，根據現場救難人員統計，共造成15名女性和4名男性死亡。

社群平台上瞬間出現大量民眾分享的影片，能看到氣爆當時的威力規模。

消防人員撲滅火勢後，德黑蘭副省長Hamidreza Goudarzi向媒體表示，引爆點應該是大樓內部，因為醫療瓦斯罐洩漏、進而導致爆炸和著火；但國營通訊社（IRNA）則是認為，此次嚴重氣爆是因氧氣罐爆炸造成，實際細節仍需相關單位深入追查。

當爆炸發生的第一時間，由於伊朗內部消息相對封閉，甚至有外電傳聞、疑似與核電廠或核武試驗有關，最終都被政府嚴正否認。
