Peristiwa 4 Maret itu terjadi sesudah pembom jibaku menyerang iringan lima kendaraan satu gerakan khusus Korps Marinir Amerika Serikat di jalan raya ramai antara kota Jalalabad, Afganistan timur, dengan perbatasan Pakistan.
The March 4 incident was sparked when a suicide bomber ambushed a five-vehicle convoy carrying a US Marine Corps special operations unit on a busy highway between the eastern city of Jalalabad and the Pakistan border.
