Senior Hamas member Imad Al-Alami died this morning as a result of injuries sustained three weeks ago while he was inspecting his personal weapon in Gaza City.
The 62-year-old died at Shifa Medical Complex, the movement's spokesperson Hazim Qasim told Safa.
On 9 January Hamas announced that one of his members was in a critical condition after he shot himself in the head while inspecting his personal weapon in his home.
He remained in the intensive care for 21 days.
Imad Khaled Namik Al-Alami was born in Gaza City on 16 February 1956. He joined the ranks of Hamas at an early age and was active in the movement's media work since its founding.
Al-Alami received a bachelor's degree in civil engineering from the University of Alexandria in Egypt, married and had six children.
He was arrested by occupation forces between 1988 and 1990 on charges of incitement and was expelled from the Gaza Strip in 1994.
He worked as a representative of Hamas in Iran then left for Syria only to return to Gaza in 2012.
Hamas elected him as Ismail Haniyeh's deputy in the Gaza Strip in 2013.
His leg was amputated in 2014 after it was injured during an Israeli shelling campaign on the Strip during "Operation Protective Edge".
