Two years ago, FRONTLINE brought you a startling portrait of everyday life in a war zone, through the eyes of children living in the besieged Syrian city of Aleppo.

There was five-year-old Sara, who had dreams in which she was shot by snipers, and eight-year-old Farah, who could tell apart rockets and tank shells based on the sounds they made when they exploded outside her home.

And there were Sara and Farah’s older siblings: 14-year-old Mohammed, who said he didn’t have any feelings left, and 13-year-old Helen, who said she just wanted her sisters and brother to be happy.

Where are they now?

With the Syrian war now in its sixth year and its death toll estimated at 470,000, FRONTLINE brings you Children of Syria. Coming to PBS Tuesday, April 19, the documentary tells the story of what has happened to these four children and their parents since you saw them last.

Also this month, we’ll bring you an encore presentation of our 2015 investigation of Russian president Vladimir Putin’s rise to power.

Here’s a closer look at FRONTLINE’s April lineup:

April 5 — Putin’s Way

Go inside Vladimir Putin’s ascent from unemployed spy to modern-day czar.

April 19 — Children of Syria

The story of four children surviving in war-torn Aleppo, and their escape to a new life in Germany. The documentary follows a Syrian family that FRONTLINE first profiled back in 2014 over three years, from the siege of their city, to the kidnapping of their father, to the struggle of becoming refugees.
