With the disease. From nbc world news headquarters in new york. This is nbc news with lester holt. Good evening. Great britain is still reeling over the beheading of a aid worker by isis. And the killer of david haines may also be a british citizen but fighting for isis. Hours after video of the brutal murder surfaced on the internet yesterday, cameron had a meeting with his military and security to discuss options. And haines killing has increased the urgency to organize a u. S. Led coalition to defeat isis. But the most poignant reaction comes from the brother of the slain hostage. Lets begin with Kristen Welker at the white house. Our brother, son, father, nephew, husband and friend was brutally and cold bloodedly murdered by isis. A griefstricken michael haines. Isis released a videoo and also threatening alan herring. Haines, 44, was a father of two and a long time aid worker captured in syria last year. My first reaction could be one of hatred. But my brothers life wasnt about hatred. David come ran vowed to hunt down the killers. Islam is a religion of peace. They are not muslims, they are monsters. And anger from the white house. Were going to beat them. They stand for nothing but what they can destroy. The latest execution could pressure the u. K. In launching air strikes. The white house has received some commitments. Australia agreeing to send 600 troops, france vowing to conduct air strikes and Senior Administration officials said today several arab countries will participate in an air campaign. There are some clearly prepared to take action in the air alongside the United States and to do air strikes, if that is what they are called on to do. On meet the press, former secretary of state james baker said despite the president s pledge of no boots on the ground, some u. S. Forces are needed. Im afraid to say what i think it will be. It will be u. S. Special ops forces and people like that on the ground. A growing threat yet again claiming another innocent life. Unfortunately it was not in our hands, it was not in the hands of the government. It was in the hands of terrorists. A new nbc news wall street journal annenberg poll show while many americas support the president s decision to take action, 68 lack confidence they can take out the group. Kerry will meet at an International Conference focused on the isis threat. And the president pledged this past week to step up the fight against isis and that means stepping into battlescar syria. Isis is one of the dangers of competing aims and alliances, locked in one of this planets bloodiest wars. Bill neely is there tonight with this report. Reporter syrian troops battling rebels who threaten the capital damascus. They have overwhelming fire pour but it is not fire power but it is not working. They are gaining ground. Ive seen syrian war planes but president assads isis is not working. Behind me they have been bombing rebel positions over there. Hundreds of times. This is a car that has gone on for three years and now cost 200,000 lives but it is a war about to enter a dangerous new phase. American war planes may be the next over syria, bombing isis. The regimes men dont like it. Is it a good thing . No no no. We dont want americans bombing our country, they say, unless they coordinate with our president. This one says america is lying. It just wont bomb isis. They trust syrian, not u. S. Air strikes. Reporter the u. S. Is preparing to enter a long and dirty war. For syrian air strikes kill civilians and not just rebels. Dozens in damascus in recent days. Syrians christians are horrified at the latest isis beheading. What they are doing, it is bar bearan things. Reporter they pray for all of the war dead, a war now on the brink of western ache strikes and a deadly new phase. Bill neely, nbc news, damascus. And while the u. S. Prepares to carry the fight for isis in syria, the battle in iraq is far from over. Millions of lives have been impacted and many uprooted from their homes and on the run and still others face an ugly ultimatum from the terrorists. Here is richard engel. Reporter the cost of doing nothing against isis is written on the faces of the iraqi christians. The militants took over last month. And now they live in a construction site and handing out food and cooking what little they have, sleeping in makeshift rooms, their lives are on the line. Hanny gurgis fled, but his brothers werent so fortunate. Translator we left 14 of us in one car when isis came. My fro brothers were following on foot but we got separated and when i looked back, my brothers werentre more. Where many of the families are from was once the largest christian city in iraq and now it is occupied by isis and mostly empty. The christians moved to erbal where a church yard is a refugee camp. Isis is giving three choices. Convert to islam, be killed or run to one of the few safe places left. Reporter those who manage to escape, pray for salvation from a group that is targeting all of iraqs ancient religious minority, International Agencies are overwhelmed. We are looking at 17 million iraqis who have been affected by the crisis and violence. Reporter that is more than half of the population . Correct. Yes. It is immense needs. We are talking millions of children affected by the crisis. Reporter at the construction site,al hanny can do is all hanny can do is wait for response from his brother. He spoke to them on the phone and said they were forced to islam and used as slave labor. They say there is only one nation powerful enough to take them on, and that is the United States. Richard engel, erbal, iraq. Back in the country with a full schedule of sunday games, all eyes on the nfl following a week of controversy involving star players in cases of domestic e.

Still fuelling pressure on the league, social media like this image of an ad by sponsor cover girl photo shopped on twitter, mocking, get your game face. I feel the nfl is in a crisis on how do you deal with the world now brought to them through social media, the backlashes there. They used to act with impunity and now they dont any more. Today hall of Famer Chris Carter became emotional criticizing the Minnesota Vikings to sit star adrian peterson, charged with allegedly abusing his 4yearold son. They did the right thing.
