NAIROBI, Kenya (AP) â?? Kenya's National Disaster Operation Centre says that two explosions in Nairobi have killed at least four people.

The National Disaster Operation Centre said Friday one blast targeted a mini-van that Kenyans use for public transportation. It says that a second blast went off in a market.

Many injuries were reported.

The attacks come the same week the United States and the U.K. issued renewed warnings about possible terror attacks in Kenya.

The U.S. Embassy says that more than 100 people have been killed in shootings, grenade attacks and small bombs in Kenya over the past 18 months.
