Wanted: a new prime minister for Turkey who should be ultra-loyal to President Recep Tayyip Erdogan, obedient but still strong enough to steer the government of a country of almost 79 million.

One week after Prime Minister Ahmet Davutoglu's shock announcement he was stepping down, there is still uncertainty over who will be the next premier, although several candidates have moved to the top of the list as the Ankara rumor mill goes into frenzy.

Experts say the link between mental illness and so-called "lone wolf" terrorists is driven by the fact that unstable individuals are often influenced by events in the news, a fact that is exploited by global jihadist groups.

Tuesday's knife attack by a 27-year-old German shouting "Allahu Akbar" left one dead and three injured in Munich.

It could be a short honeymoon for Brazil's interim president Michel Temer, who replaces a deeply unpopular leader but inherits many of the same problems.

Brazilians are hoping their country can finally move on from a months-long battle over suspended president Dilma Rousseff's impeachment, which distracted their political leaders from a laundry list of woes, including the worst recession in decades.

Militants inspired by the Islamic State group's ideology are seeking to benefit from the desperation of young Palestinians to strengthen their foothold in the Gaza Strip.

But the Salafists in the enclave tread a fine line to avoid conflict with Hamas, the Islamist movement which has ruled the strip for a decade but does not share IS's world view.

North Korea's first ruling party congress for nearly four decades proclaimed the formal start of the Kim Jong-Un era, but the event was more notable for nods to the past than promises for the future.

Analysts looking for signs of substantive policy shifts or reforms under the young leader were given little to go on, as the 33-year-old Kim signaled few changes at home and a continued foreign policy of belligerent defiance backed by an expanding nuclear arsenal.

Brazil's Senate is set to start voting Wednesday on whether to open an impeachment trial against President Dilma Rousseff. If a simple majority is reached, she will be suspended automatically for six months and Brazil's political crisis will enter dramatic new territory.

But while Rousseff faces the possible end of her political career, Brazil's problems appear far from over. Here's a look at how Latin America's biggest country got into the mess -- and what could happen next.

North Korea has wrapped up its first ruling party congress in nearly four decades.

Here are five things we learned from the four-day gathering of the isolated, nuclear-armed state's top decision-making body.

One Brazilian is accused of taking bribes, another with hiding a secret bank account, a third with trying to help a man escape prison.

So who are they -- hardened conmen? Mobsters?

By letting go of his prime minister after just 20 months in the post, Turkey's President Recep Tayyip Erdogan has shown his iron will to create a presidential system where one man has total authority.

Ahmet Davutoglu, who served as premier since Erdogan became president in August 2014, in his farewell statement vowed undying loyalty to the Turkish strongman and never to utter a "single word" of criticism against him.

Three years ago, Albert and Yassin left their homes in Kosovo and Albania to wage jihad in Syria. Now they're back, swelling the ranks of jihadists in a region the Islamic State has called a "new front" in Europe.

Yassin, 30, who now works as a halal butcher in a downtrodden suburb of Albania's capital Tirana, refused to give his real name out of fear of repercussions.
