    Initial investigation identified the injured as a Briton and a Canadian. A spokesman of Vajira Hospital identified the Briton as Jeffeny King, 28, who was passing the house at the time of the blast. He was injured by shrapnel in his left shin.

    Three cars were damaged in the powerful explosion, which took place at about 2:05 p.m. (0505 GMT), one of the cars parking several meters away on the opposite side of the four-lane road.

    It is reported that Gen Prem was in his residence when the bomb exploded.

    Police immediately cordoned off the area to collect the evidence.

    Police said the bomb was placed under a chair next to the police booth. The blast destroyed the chair and shattered window glass of the booth.

    Prime Minister Thaksin Shinawatra, who was on the election campaign tour in Chanthaburi, said he had not received an official report on the bomb yet but he believed someone was trying to create a situation.

    He said police would try to find out the masterminds of the bomb and bring them to justice. Enditem
