ANKARA, Turkey (AP) — Two nearly simultaneous explosions targeted a Turkish peace rally Saturday by Kurdish activists and opposition supporters in Ankara. At least 86 people were killed and nearly 190 wounded in what appeared to be suicide attacks, Turkish officials 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.
