Two supporters of Nairobi senator Mike Sonko died Wednesday after being crashed at the Muthurwa footbridge.

The two were part of a group that was being ferried from the Jubilee Party Headquarters after Sonko’s unveiling of Polycarp Igathe as his running mate for the Nairobi gubernatorial seat.

Reports indicate that the two were standing in the moving lorry as it passed under the bridge, crashing their heads in the process.

They died on the spot.

The supporters had accompanied the Senator to the party offices where he was issued with his nomination certificate by Deputy President William Ruto.
