The explosion from a remote-controlled landmine was targeted coppers collecting tax from buses at a busy area in Wadajir district, south of the seaside Somali capital.
The maimed victims were rushed to a nearby hospital by ambulances for medical treatment and there was no immediate claim of responsibility for the bus station bombing.
The security forces sealed off the scene and conducted an operation which ended in vain as no arrest was made for the attack, which comes amid deteriorating security situation.
The city witnesses in the past weeks surge in killings against Tuk-Tuk drivers with police facing pressure from the public to deal with the insecurity and acts to destabilize the city.
Police blamed al-Shabaab
...... the Islamic version of the old Somali warlord...for the attacks in the city after losing ground to SNA and allied clan militia in central regions since last year.
