Germany has been shaken by a wave of brutal attacks. The pressure is mounting on Chancellor Angela Merkel to explain how she plans to protect the German people.

Terror has come to Germany in the form of four shocking attacks. There is no apparent link between the incidents. But three of the atrocities were carried out by young men who came to Germany as refugees. That has prompted some to ask what – if anything – this series of attacks has to do with Chancellor Angela Merkel’s decision last year to open up Germany’s borders to refugees. How will Merkel respond? And how can her government prevent further attacks in the future?

Prof. Isabella Heuser-Collier – she is the Director of the Department of Psychiatry at Charité. She says: "No, Merkel is not to blame for the terror coming to Germany, but she is to blame for not sufficiently and convincingly explaining her solutions. Treating the people in a maternalistic way by simply saying " I know what I am doing, dont you worry, we'll succeed" is not reassuring. People need information, even if it is complex and complicated.”

Alan Posener – british german Author at the Berlin daily newspaper "Die Welt", he says: "Who's to blame for Islamic terror? Islamic terrorists and dictators, of course."

Amir Musawy - is the Berlin Bureau Chief of the Iraqi TV channel Al-Iraquia TV. Musawy is the co-author of the documentary film “Bureaucracy of Terror - An Inside Look at the Islamic State”. He says: "IS terrorists communicate between each other effectively so they giving the European rights better chance to embracing Merkel in Europe and Germany.It is the Time to Merkel to be more honest with public about the fact that, Germany should live with international Terror Danger."

It all began last Friday, when tanks appeared at strategic locations in Istanbul and military jets and helicopters were spotted over the capital Ankara. The uprising quickly crumbled but hundreds were left dead or wounded.

Alan Posener - british german Author at the Berlin daily newspaper "Die Welt", he says: "Nobody is about to give Erdoğan a blank cheque. But demonising him will help neither Turkey nor the West."

The US has been shaken by a series of killings of black Americans by white police officers. Just as disturbing: the shooting of five policemen in Dallas by a black sniper. President Obama has been trying to heal the nation. But the wounds are deep.

The US has been shaken by a series of killings of black Americans by white police officers. Just as disturbing: the shooting of five policemen in Dallas by a black sniper. President Obama has been trying to heal the nation. But the wounds are deep.

Shock, despair and anger as America was confronted with images of white police officers shooting and killing two black citizens – seemingly without provocation. One thing is certain: these are not isolated incidents. Then, at a peaceful march in Dallas against police violence, five white officers are gunned down. The shooter: a black sniper.

At a ceremony to honour the five slain officers, President Obama said that the people of the US are not as divided as it might seem. But he also spoke of what he called the “deepest fault line” in American democracy. The president’s critics say he has not done enough to improve the situation of minority communities.

How racist is America? And how can racially-motivated violence be stopped?

Erik Kirschbaum is a New York native and long time Germany correspondent, currently for the LA Times. He says: “The united states feels like a powder keg with deep political, economic, social and racial divisions threatening to erupt into a bigger explosion.”

Rieke Havertz is a senior editor at ZeitOnline. She says: "The American society has failed to address the issue of racism for years. President Obama has to ask himself if he has been too defensive in making this his agenda."

Karen Taylor is an activist with the “Black People in Germany Initiative”. She says: "More black people will be killed as long as racism is rooted structurally and institutionally in our society. This applies to the United States as well as for Germany."

The Brexit vote in the UK leaves the European Union facing huge challenges, with some predicting that it might even break up. There can be little doubt that the EU needs to reform. But does that mean more or less Europe?

“The EU needs to change or it will die,” says Guy Verhofstadt, leader of the Liberals in the European Parliament.

How should the EU respond to the fears of many of it citizens when it comes to issues like social inequality and immigration? And how best to react to the rise of populist anti-EU parties across the continent? The people of the EU want answers. But will those answers come in the form of a new vision for the bloc, or simply more pragmatism?

Malte Lehming is the editor of the opinion page of "Der Tagesspiegel". He says: "The Brexit could be good for Europe. The turmoil in Great Britain after the referendum are a deterrent to other nations on the continent from embarking upon a similar experiment."

Derek Scally works for the Irish Times. He believes “Brexit is a failure of the entire European political class -- including Germany. Everyone says they are shocked yet instead of fresh ideas and now ways of working, everyone is serving up old wine in new bottles

Hannah Cleaver is a DW news journalist. She says: “It's difficult to decide which will be the biggest loser from Brexit - Britain or the EU.”

Europe is in disarray after last week’s referendum vote in the UK to leave the European Union. Great Britain it seems is out. What will really happen after the Brexit vote: will other member countries now follow the British example?

One thing is sure: Eurosceptics in other EU countries are already calling for their own referendums on membership, prompting fears that the whole European house could come tumbling down.

Will the UK now trigger Article 50 of the European Treaty and begin its departure from the EU? Or have the Brexiteers and their talisman Boris Johnson lost the courage of their convictions? London says it needs time to consider its next move. But key European leaders are saying they will not accept a long period of uncertainty.

The question is though: who is in charge in London? Will fresh elections be necessary? And what about the future of Scotland, where another vote on independence looks increasingly likely?

Ulrike Guérot, the Director of the European Democracy Lab, says:"The Brexit is a wake-up call," (that the EU can't continue with business as usual. We have to make sure events don't cascade. And)) now we have to ponder a very different Europe: in parliamnetary terms, democratic terms, and social terms."

Andreas Kluth, Berlin Bureau Chief The Economist. He says: "The EU should, first, strive for a lenient and gracious deal that keeps Britain close to the continent and, second, reform itself in a hurry."

Ursula Weidenfeld, business editor, she says: "Keep calm and carry on: England made a mistake, but now both sides should work to not let it become also an economic disaster.”

The charge: systematic, state-sponsored doping. The official response: zero tolerance. The International Olympic Committee has backed a ban on Russian athletics imposed by the International Athletics Federation. Russia has vowed to lodge an appeal.
