...this type of explosion is similar to the recent bombing incidents that took place at the Interior Ministry and Santi Asoke Foundation, he said.

Police immediately cordoned off the area to collect the evidence. When the blast went off, there [were] no police in the booth. Initial investigation identified the injured as a Briton and a Canadian who were passing the house at the time of the incident.

A spokesman of Vajira Hospital identified the Briton as Jeffeny King, 28, and Merry Ruszell, a Canadian, 55. King was injured by shrapnels in his torso and both legs, while Ruszell at his arms.

Police said the bomb was placed under a marble bench next to the unmanned police booth. The blast destroyed the bench and shattered window glass of the booth. The explosion damaged three cars parked nearby and opposite side of the road.
