One in six children live in war zones

According to a report published Thursday by global charity Save the Children, more than 357 million children live in war and conflict zones, an increase of roughly 75 percent from the early 1990s.

Around half of those affected, some 165 million children, live in "high-intensity" conflicts. Youngsters in the Middle East are most likely to live in an area classed as a war-zone, with two in five children living within 50 kilometers (31 miles) of a "conflict event." Africa was ranked as second-most dangerous region.

There has been a marked increase in the killing and maiming of children. Since 2010, the number of UN-verified cases of has gone up by almost 300 percent.

Increased urbanization key factor

The report blames several factors for the overall increase. It says conflicts today tend to be protracted and are often fought in densely populated areas, with "attacks on what should, by any law or civilized standard, be safe places for children — such as schools and hospitals — also becoming a new normal in conflicts," said Save the Children CEO Helle Thorning-Schmidt.

Save the Children also says that "increasingly brutal tactics are being utilized" abusing children as suicide bombers and targeting kids in schools and hospitals as well as using so-called indiscriminate weapons like barrel bombs and cluster munitions.
