Tim Cocks-Tim Cocks is a Reuters correspondent in Iraq.-

This month we reported that the number of civilians dying violent deaths in Iraq had hit a fresh low since the 2003 U.S.-led invasion -- about 125 for September.

Sounds like a lot, but for a country that only two years ago was seeing dozens of bodies pile up in the streets each day from tit-for-tat sectarian killing, it was definitely progress.

And as I prepare to end my assignment in Iraq this week, I need no argument from numbers to convince me that things are better here than when I arrived in Feb. 2008.

During my first few months, militants loyal to to anti-American cleric Moqtada al-Sadr were raising hell in Baghdad, firing mortars and rockets at the Green Zone almost every hour. We could hear or feel them thud on impact, especially when they fell short, on our side of the Tigris.

A rocket hit the BBC building opposite us, causing a blast loud enough to shake our windows, although thankfully no one at the BBC was hurt by the strike.
