Egypt's army has destroyed a major illegal tunnel crossing the Egyptian border in North Sinai, a military spokesman said in a statement on Sunday.
Security forces killed two "very dangerous" militants in the raid on the tunnel, with two 4x4 vehicles also destroyed, according to the statement.
The army said it discovered the tunnel while carrying out operations to stem Islamist insurgency operations in North Sinai – an insurgency that has killed hundreds of police and army personnel in recent years.
Since 2011, Egypt's military has been destroying illegal tunnels running from North Sinai to Gaza, with the aim of halting the smuggling of weapons and ammunition to militants.
North Sinai has borders with both Gaza and Israel.
In October 2014, Egypt said it destroyed a total of 1,813 tunnels used for weapons smugging. The army continues to periodically discover tunnels and destroy them.
In July 2015, the Egyptian cabinet issued a decree banning 4x4 vehicles in those parts of North Sinai designated by the military as areas of ongoing anti-insurgency operations.
