The five-kilometer junction is in Hodan District, a commercial part in the city.

The number of casualties has not yet been established.

President Mohamed visited scene at Zoobe then went to various medical facilities to check on the injured.

There was no immediate claim of responsibility, but Al-Shabaab terrorists carry out frequent bombings in the country.
