Germany's Muslim community is bracing for a culture shock when masses of Arab migrants join millions of residents of Turkish origin.

But experts suggest the change could be positive for it could broaden outlook, and say fears of Islamist radicalism may be overblown.

The double suicide bombing on a peace rally in Ankara has raised a feud between the government and Turkey's main pro-Kurdish party to a new level, widening a dangerous polarization as Turks head to November 1 polls.

The carnage has put the charismatic leader of the Peoples' Democratic Party (HDP) Selahattin Demirtas on a collision course with President Recep Tayyip Erdogan, who he accuses of presiding over a "mafia state" responsible for Saturday's bombings that killed at least 97 people.

Stones or bullets? For now, the Palestinian leadership hopes protesters have learned lessons from the second intifada and stick to the former in clashes with Israeli security forces, officials say.

During that uprising, from 2000 to 2005, armed Palestinian security forces confronted the Israelis.

Cruise missiles fired from warships, the latest jets pounding far-off targets: Russian President Vladimir Putin's show of strength in Syria looks aimed at proving that a resurgent Moscow can rival the West, analysts said.

Since late September Russia has flexed its muscles in a bombing campaign across the war-torn country that has put a U.S.-led coalition in the shade and angered Washington and its allies.

Turkey is giving a European Union plan to assist the country in hosting over two million Syrian refugees only a lukewarm reception, indicating funding needs to be drastically increased and lamenting shortfalls in help over previous years.

The EU hopes that helping refugees inside Turkey will discourage Syrians from taking perilous sea and land routes to seek new lives within the bloc after an unprecedented influx in the last month.

As Barack Obama's secretary of State, Hillary Clinton loyally carried out his agenda, but since mounting her presidential bid she has split with the White House on several key issues, including global trade.

Drilling in the Arctic Ocean is too risky, she argues. Deportations? The administration's record rate of sending undocumented immigrants home is unnecessarily "breaking up families," according to Clinton.

Iran's nuclear deal with world powers has bolstered its central role in efforts to end the spiraling Syrian civil war, bringing Tehran back to the world stage, analysts say.

Though the conflict seems trapped in a military mire -- Russia's air campaign on behalf of Syrian President Bashar Assad being the latest intervention -- Iran is seen as a crucial diplomatic channel.

The deadly U.S. attack on a hospital in Afghanistan, which U.S. officials have called a "mistake," leaves open the possibility that the decision to open fire exceeded the authority under which American forces have operated since their combat mission ended nearly a year ago, officials say.

U.S. officials have declined to discuss most circumstances of the attack in Kunduz that killed 22 civilians, since American and Afghan investigations are under way.
