Today, secretary of state john kerry left for europe and new peace talks on syria, saying that thehe challenges nothinin less than to chart a course out of hell. His words come as the u. S. Against isis in syria and iraq. Heres david martin. Reporter aircraft continue to destroy isis targets every day, but the Obama Administration is frustrated by the glacial rate of progress and abt to ramp up the war in ways that could increase the risk of american combat casualties. One plan would use aapache helicopter gunships, which are much more vulnerable to ground fire than jet aircraft, to fly missions in support of iraqi troops trying to retake the city of ramadi. Other proposals would incncase the n nber of american advisers in iraq and place them closer to the front lines. As defense secretary carter made clear in congressional testimony, there is a new sense of urgency about deeffect isis. I cant tell you how long it will take, but i think that it needs to be soon,hich is why re so intent upon strengthening our effort. Reporter last week, Master SergeantJoshua Wheeler became the First American killed in wounded in a raid on an isis prison. And carter said there would be more special operations raids to come. That signals a fundamental change in what had been until now a war of attrition. Airstrikes kill enemy fighters and destroy their equipment without dislodging them from key cities like ramadi and mosul in iraq, and al raqaa in syria, where the headquarters for isis is located. U. S. Military officers complain about how slowly the iraqi army is moving to retake ramadi. In syria, u. S. Backed fighters are doing much better but there just arent enough of them to drive isis out its headquarters in al raqaa. Scott. Pelley david martin, thanks. Well, the key to Northern Iraq is the city of mosul, which has been occupied by isis for more than a year. Iraqi forcrc have pledged too ke the cityy of one Million People back, but noct has happened. Elizabeth palmer is in Northern Iraq for us tonight. Liz. Reporter the operation to take mosul back should have gone ahead about six months ago, and yet the iraqi army is stalled more than 100 miles away. Commanders here say that the iraqi army simply cant do it alone, but even with american firepower and intelligence, there is another huge problem. The iraqi army is largely shiite. Mosul is a sunni city, and that means its filled with people who actually, crazy as it sounds, support isis, or at least they think rule by isis is preferable to having their city taken by a shiite army backed by a corpt government in baghdad. Bottom line, this is not going to happen any time soon. Pelley the two major factions of islam opposed to each other there around mosul. Lizalmer, thank you verer much. Every day, three children are killed and 470 injured in car they were hit by the front seat. Kris van cleave has our investigation.

What were trying to do is show how absolutely ridiculous the federal standard is. Reporter this is the only test required to pass the federal standard, a standard so weak, that even a banquet chair passes. This is strong enough. Accccding to the government, is is strong enough. Reporter all the seats we tested met or exceeded the federal requirements, but in some, failures like this can still happen. Do car makers know this is an issue . Yes. Some of them have made their seats stronger. Reporter how do i as a consumer know if i hava a strong seat or a weak seat . Theres nooay of knowing as a consumer. Reporter thats because seat testing is not included in current star safety ratings. Vehicles can have five stars and still have weak seats. This is a beltintegrated seat. Reporter longtime accident investigator Ken Saczalski has been trying to get the national Highway Traffic Safety Administration or n. H. T. S. A. To requiretronger seatsts since 1992, when he spoke to ed bradley on cbs 60 minutes. Its an inadequate standard. Its flawed, as far as im concerned. Reporter has that changed . No it hasnt. Its basically the same today as it was then. Its a worthless standard. Reporter n. H. T. S. A. s own researchers also warned of the issue in 1992 citing examples of major or fatal injuries when seat backs collapsed. N. H. T. S. A. Declined to speak to 60 minutes back then saying only the agency was investigating ways to strengthen the standard. Kris van cleave from cbs news. Reporter current n. H. T. S. A. Administrator Mark Rosekind turned down our interview request and had nothing to say when we caughtt up with him. Happy birthday to you. If they had changed the gogornment safety standndds to where the seat back wouldnt fail then we would still have a sixyearold running around. Reporter n. H. T. S. A. Sent a statement saying in 2004 the agency decided to stop looking into seat back strength.
