Hamas chief Yahya Ibrahim Hassan Sinwar, who was killed by Israeli military on 16 October, was hiding in tunnels since the Hamas terror attack on Israel
Yahya Sinwar's household was among the few thousand Palestinian Arabs that were forced to leave during the conflicts that preceded Israel's establishment, thus he carried strong feelings against Israel and joined Hamas as soon as it was founded in 1987.
As heavy fighting continues in Gaza between Israel and Hamas, with the war entering its 66th day and Israeli forces being relentess in their pursuit of attacking Hamas, Israel Prime Minister Benjamin Netanyahu called on the terror group to 'surrender now' and warned that 'it is the beginning of the end of Hamas'.
