NAIROBI — A car bomb exploded on Saturday at a checkpoint near the Somali Parliament, killing at least eight people and injuring 16 others, medical and police officials said.

“We have confirmed eight people killed and 16 others wounded in the blast,” according to a statement issued by Aamin Ambulance, a privately-owned medical transportation service.

A separate blast from a roadside bomb in Mogadishu hit a police vehicle patrolling near Kenya’s border with Somalia on Saturday, killing several of the 11 officers inside, a police spokesman, Charles Owino, said.

The toll from that attack was not immediately clear, he said.

Another blast, at a busy junction leading to the airport of the Somali capital, Mogadishu, and known as K4, did not cause any casualties after it was intercepted by security services.
