Hamas names Oct 7 mastermind Sinwar as leader after Haniyeh assassination

Sinwar, the architect of the most devastating attack on Israel in decades, has been in hiding in Gaza, defying Israeli attempts to kill him since the start of the war.

"The Islamic Resistance Movement Hamas announces the selection of Commander Yahya Sinwar as the head of the political bureau of the movement, succeeding the martyr Commander Ismail Haniyeh, may Allah have mercy on him," the movement said in a brief statement.

News of the appointment was greeted with a salvo of rockets from Gaza from the bands of militants still fighting Israeli troops in the besieged enclave.

Sinwar, who spent half his adult life in Israeli prisons, was the most powerful Hamas leader left alive following the assassination of Haniyeh, which has left the region on the brink of a wider regional conflict after Iran vowed harsh retaliation.

Israel has not claimed responsibility for the assassination but it has said it killed other senior leaders, including Hamas deputy leader Saleh al-Arouri, who was killed in Beirut, and Mohammed Deif, the movement's military commander.

Born in a refugee camp in the southern Gaza city of Khan Younis, Sinwar, 61, was elected as Hamas' leader in Gaza in 2017 after gaining a reputation as a ruthless enforcer and an implacable enemy of Israel.

He was formerly head of the Al-Majd security apparatus which tracked, killed and punished Palestinians accused of collaborating with Israel’s secret service before he was jailed.
