ANKARA, Turkey (AP) — Two bomb explosions targeted a peace rally Saturday by leftist and Kurdish activists in the Turkish capital of Ankara, killing 86 people and wounding 186, the country's health minister said.
Urbanization — the expansion of cities — is on the rise. People across the globe are heading into urban areas looking for work, education and health care. Others arrive, fleeing wars and natural disasters. Without the proper planning, the rapid increase in urban areas, especially in developing countries where most growth is happening, can lead to some big problems.
