states from seven muslim majority countries. we re tracking that this hour and also the issue of who will pay for the wall. president trump wants to build along the u.s./mexico border remains unresolved now. we want to show the reality of what s happening along the southern border. pard three of ed lavendera s report on the wall. he got access to a han underground network of drug-smuggling tunnels, that exist from mexico right underneath the border into the u.s. for years the vigilance along the u.s. southern border has been growing. hundreds of miles of fencing, border patrol agents criss-crossing the remote terrains and urban streets. ground centers and high-powered cameras keep constant watch. but now smugglers go where the cameras and eyes can t see them. we are in a tunnel underneath otai mesa, california, south of san diego. on the border with tijuana,
and what we see in front of us over there is the new fence. a border fence that first built to keep ow migrant sess now meant to hold back smuggleres and a terrorist threat, most recently isis sinai. we know what s out there and that s what it is. we have to guard against it. egypt has been struggling. they have been succeeded in destroying nearly all the smuggling tunnels, forcing the smugglers to look further south. smootheling has become more lucrative and more dangerous. we have seen definitely an increase in these very violent attempts to cross into the israeli border. as the threat evolves along the sinai border, so does israel aes military, keeping watching against an enemy that remains, for the most part, unseen. cnn, southern israel. stranded in the cold, migrants are being forced to wait at the greek macedonia
of the muslim brotherhood. let s bring ambassador ross and he served as a advisor to clinton. where are we now, mr. ambassador? we re seeing what is a profound conflict within egypt. clearly the egyptian military and president el sisi felt they ve been making headway in terms of taking on isis and the muslim brotherhood. this is the second anniversary of the removal of morsi. and president el sisi assuming power. the real fight has been in sinai. we ve seen the egyptians shut down the smuggling tunnels from sinai into gaza. they run into both directions. clear a wide area around the city of raqqa.
and then the other tuns which i went into on a number of occasions which go from gaza into egypt. these are the smuggling tunnels basically used to bring in food, bring in gas, livestock, anything else that the gazans need. and also, according to israel, are used to resupply hamas. that is how they get their weapons into gaza within this blockade. certainly was interesting seeing these tunnels. they very basic. the ground is clay and sand, not particularly conducive to these tunnels. a number of collapses. we have seen over the years israel bombing them quite significantly. but they do seem to keep emerging, and egypt trying to cut back on these tunnels. hamas has a number of years in experience in building these tunnels. brooke? israel presumably want to go destroy the tunnels to choke off the point in which hamas is using tunnels to smug, to get the weaponry in. maybe perhaps originally coming
underground passageways to launch attacks inside israel. just this morning, there were two squads of hamas terrorists who came through tunnels. they entered israel in the south. they tried to attack two different areas where civilians are just trying to conduct daily lives. it shows who hamas is. hamas is an extremest deadly terrorist organization. worst of all is the people of gaza are suffering because of hamas. they didn t want this, wolf. tunnels have long played a role in gaza. i want to talk about that with a cnn correspondent paula hancocks. you have actually been in some of the tunnels. that exist between egypt and gaza. these were smuggling tunnels. when i went down a few years ago, there were hundreds of them. the sort of things that were use f ful is to bring basic goods, building materials.
