Secretary of State Tillerson is arriving in Turkey today, and it’s all but certain his meetings there will include discussions of the simmering tensions in Syria, including the Turkish offensive against U.S.-backed Kurds in Afrin.

Why it matters: The Afrin assault is just one of several violent clashes in recent weeks to expose the overlapping and contradictory interests coming to a head in Syria. The powers operating in the region appear to be deepening their involvements, even as ISIS has largely been beaten back.

The meetings come after a week UN High Commissioner for Human Rights Zeid Ra’ad Al Hussein called this “one of the bloodiest periods of the entire conflict” in Syria.

The state of the standoff
  • Turkey is attempting to push back Kurds in western Syria.
  • Syria, along with Russia, is pushing back rebels in eastern Syria.
  • Other key players: The U.S., Iran, Israel and al-Qaeda, not to mention ISIS.
Recent events

Turkey entered the war for the first time as an overt combatant when it launched the Afrin offensive in January. The Kurdish forces, labeled terrorists by Turkey, were a crucial U.S. ally against ISIS.

That offensive has left the U.S. in a bind for several reasons:

  • The two countries are NATO allies and have both said they want Assad removed from power. But the U.S. has aligned itself with the Kurds, leaving it at odds with Turkey.
  • Turkey and Russia coordinated in the offensive, showing they’re willing to work against the U.S. in the short term even though they have divergent end goals for Syria.
  • If Turkey continues to Manbij, as is the stated objective, it raises the prospect of direct clashes with U.S. forces there.

Israeli jets attacked Syrian government and Iranian targets near Palmyra after claiming an Iranian drone had entered Israeli airspace.

  • An Israeli jet was shot down, apparently by the Syrian government. It's believed to be the first Israeli jet downed by enemy forces since the 1980s.
  • It is a direct confrontation between Israel and Iran, raising the likelihood of military escalation.
  • Axios contributor Barak Ravid reports exclusively that Israel sent a Top Secret cable after the clashes to embassies around the world. Get the details.

The U.S. launched rare strikes against pro-Syrian government forces east of the Euphrates deconfliction line this month after what the Pentagon called an “unprovoked” assault.

  • This is raising questions about whether the U.S. forces in the region, deployed to fight ISIS, will be drawn into the civil war, per the AP.
  • The U.S reportedly killed scores of Russian mercenaries in the strikes, possibly the deadliest clash between Russians and Americans since the Cold War, per Bloomberg.

A joint Syrian and Russian air campaign killed hundreds of civilians in Eastern Ghouta and in Idlib, per the AP.

  • There are also reports from humanitarian workers on the ground that Syria’s government has launched chlorine gas attacks, Reuters reports.

Al-Qaeda linked rebels also recently downed a Russian jet, per the AP.

  • The UN Security Council discussed the conflict on Wednesday, and Russian and U.S. diplomats there blamed one another for hampering peace, CBS reports. The UN envoy for Syria urged the powers fighting in Syria "to de-escalate immediately and unconditionally."
  • The latest meetings in Vienna and Sochi about a political future in Syria didn't produce a political solution, and in Sochi led to a walkout, per CNN.
  • Turkey, Iran, and Russia have plans to meet in the next month, potentially in Kazakhstan, to discuss Syria, per Reuters.
The bottom line:

The key players are further entrenching themselves — and one another — in the conflict. It's not at all clear what the end game is, given the violent disagreements over what an acceptable resolution looks like.

Exclusive: Facebook cracks down on political content disguised as local news

Facebook is rolling out a new policy that will prevent U.S. news publishers with "direct, meaningful ties" to political groups from claiming the news exemption within its political ads authorization process, executives tell Axios.

Why it matters: Since the 2016 election, reporters and researchers have uncovered over 1,200 instances in which political groups use websites disguised as local news outlets to push their point of view to Americans.

Nationalism and authoritarianism threaten the internet's universality

Governments around the world, prompted by nationalism, authoritarianism and other forces, are threatening the notion of a single, universal computer network — long the defining characteristic of the internet.

The big picture: Most countries want the internet and the economic and cultural benefits that come with it. Increasingly, though, they want to add their own rules — the internet with an asterisk, if you will. The question is just how many local rules you can make before the network's universality disappears.

The Democratic fight to shape Biden's climate policy

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.
