Woodruff the demonstrations came on the heels of sometimes violent protests over the weekend in pakistan, niger, jordan and algeria.

Woodruff the on going conflict in yemen intensified today. The countrys been a stronghold for alqaeda in the arabian peninsula, one of the most active and dangerous branches of the islamic terror network. Today, violence rocked the country. Gunfire and explosions erupted in yemens capital city, sanaa, as government and shiite rebels battled near the president ial palace. Streets emptied and the heavily armed rebels, known as houthis seized control of state run media. The houthis have been in a tense standoff with Government Forces since taking over much of sanaa last september. Since then, the u. S. Backed government of president Abed Rabbo Mansour hadi has seen its influence severely weakened. The shiite rebels have now carved out large swaths of northern yemen and extended their reach westward. Theyve vowed to wipe out the sunni forces of alqaeda in the arabian peninsula, which holds sway in much of central yemen. A. Q. A. P. Has claimed responsibility for a number of terrorist attacks, including the Charlie Hebdo shootings in paris. For more on what drives this violence and yemens links to global terror, im joined by abdulwahab alkebsi, of the center for International Private enterprise. He was born in yemen and regularly visits the region. We we canal you to the program. So theres been instability in yemen for a long time as we know. What is different . Whats significant about todays events . Tads events are very significant. Didnt start today. It started saturday when the houthis rebels arrested the president s chief of staff and took him to saba in the north and there was negotiations for his release. Suddenly today they go to the president ial palace, surround it and a battle broke out. Fortunately, there has been a ceasefire since about 4 30 p. M. Local time and calls for a meeting tomorrow for the president , the government, the houthis and two houses of parliament to try to find a solution moving forward. Forward. Woodruff help us understand more about who the Different Groups are in yemen. There are many Different Groups. To show the conflict today as the government against shiite rebels from the north is oversimplifying i think. To explain, in the battle today in sanaa had put million forces. The houthis have a core group that are completely Different Group and then todays battle was between them and the president ial guards. Responsible to protect the president s palace. The Republican Guards were a part of that. These are forces known to the former president. All of this, the regular army, the military stayed aside and didnt even fight the war. So its more complect to say shia against sunni and also makes it force. It is not that simple. Woodruff what we hear in the United States when we hear about yemen we think of al quaida and the arabian peninsula. Of course. How is aqap affected by whats going on and what could happen in sanaa and elsewhere. Terrific question. In the one hand, the how the houthis are facing al quaida and are defeating them. Right now, the houthis seem to be gearing up for a strong battle between them and the aqap. Woodruff statement theyre fighting the regime . Thats right. Now, at first sight, you think theyre doing something good for us fighting al quaida, right . So al quaida is getting weaker because of that. But, on the other hand, when we make this battle between them as one between shia and sunni, it creates such the recruitment cry for al quaida for the sunni fanatics to join them, who want to protect sunniism, they become recruitment fodder for al quaida to fight. So, again one hand they seem to be allies with us fighting al quaida, but at the same time al quaida is benefiting to recruit more supporters for them. Woodruff so is the United States rooting for one side or the other . The u. S. Has been backing backing the current president put he sooms to be in a very difficult position. He is in a difficult position. I dont envy him at all. At the same time, the United States policy in yemen is from a security idea. It should be. The reason were in yemen is because of the threat of al quaida which has shown it can hit in the United States in paris with the Charlie Hebdo attacks. The polls ials includes support for the political policy moving forward. The United States is the biggest supporter of the political process and without that it cannot get better. The economic support and growth is missing, creating jobs for yemen so the people dont become recruitment fodder. These are young men without a job and future, and they need that and find friendship and families with the houthis and al quaida. We need more jobs in yemen. Woodruff a theme were hearing across the region. Thank you very much abdulwahab alkebsi. We appreciate it. Woodruff from yemen we now turn to europe. This months deadly terrorist attacks in france continue to loom large across the continent. Today e. U. Officials called for an alliance with muslim majority countries in the fight to secure europe. The newshours chief Foreign Affairs correspondent Margaret Warner is on assignment in london, where she looks at how britain is reacting. I spoke to her a short time ago. Welcome, margaret. I know you just arrived over the weekend, but are you finding and talking to ordinary british citizens that there is a feeling, a heightened sense of anxiety worry . Yes, there is, judy. A sense of uneasiness. The people feel that there is not only a chance of a parisstyle attack here but more likely. Yesterday on the street cafes in south kensington, one woman said she found it quite scary the terrorist attacks happened so close by. The manager of a nearby cafe shared her view of the risk to the city. It makes you suddenly think that something that happened so close could happen here as well. It does make you think you would like to see that something is being done. You would like to see security is heightened and it is being taken seriously. Obviously, this is one of the more popular cities in the world, definitely under threat. So were definitely threat, afraid and have phobias but as long as the people are altogether, its okay. Reporter thats it, judy. British citizens have been dealing with terrorism on their soil for a very long time certainly since the irish Republican Campaign bombings of the early 1970s. There was the 2005 underground bombing attacks here in london that killed close to 60 people, the 77 attacks, just a year and a half ago for two british muslims who were converts actually, hacked to death an army officer, saying it was to avenge the killings of muslims overseas by british soldiers. So one retired teacher said to me yesterday, im not saying were used to it, but weve learned to enture it. Woodruff so margaret we heard one of the people you talked to, the woman saying she hopes the government is taking all this seriously. What is the British Government doing . Reporter well, judy, the governm actually stepped up the threat level to severe last fall which is essentially saying they think a terrorist attack is likely and is a much higher threat level than before in quite a long time. At that point they stepped up security at all the obvious public buildings in a visible way but also in way not visible. This coincided with the two spokesmen of the Islamic State calling on supporters in the countries that are part of the socalled antii. S. I. L coalition u. S. , canada and most to have theine countries that if they couldnt fight in iraq or syria they should help in terror attacks at home. There have been three major terrorist plots foiled that would have definitely have resulted in more deaths and the counterterrorism chief in Scotland Yard said the same last year. They had been rounding up suspected plotters for quite some time. On a completely different front, today it came to light that the a minister David Camerons cabinet had written a letter to all 1100 imams of 1100 mosques in britain calling on them to root out exremmists voices in their midst and to preach to young mucks our their faith in islam can be compatible with british identity. So i think theyre moving forward on many fronts including a call by Prime Minister cameron for surveillance powers. Woodruff whats the reaction in the Muslim Community to all this . They took great homage and said they would be held to a different standard than christian clerics when violence was created against christians and suggested there is something incompatton. That said, there is a great tension here or certainly an undercurrent of unease i would say, with the Muslim Leaders saying they are held to a different standard but many nonmuslim britts telling us they dont think muslims have been vocal enough against the violence committed in their faith. We know there are steppedup protection of jewish sites. What do you see of that in Great Britain . The same is true here. Last friday in response to paris and in response to the request from the Jewish Community the u. K. Stepped up security at jewish sites especially schools, they wrote to the parents of every child in a Jewish School in the country promising increased protection and this very night very security briefings held in many, many Jewish Schools across the country. Woodruff Margaret Warner, thank you reporting live from london and we look forward to your reports for the rest of the
