Khaled Abu Sada, a Palestinian ambulance driver, has been helping to save lives in the Gaza Strip for more than a decade. He was first interviewed by Al Jazeera three years ago.

Returning to the Palestinian enclave as Al Jazeera English celebrates its third anniversary, Khaled reports what has and has not changed over the past few years.

Facing difficulties such as the destruction of his house during Israel's war on Gaza and the loss of close friends, Khaled also comments on political issues that affect his life every single day.
