LOCKERBIE, Scotland (Reuters) - Burglars took advantage of the 10th anniversary of one of the world‘s worst plane crashes to rob a number of houses around the Scottish town of Lockerbie, police said on Tuesday. "Police in Lockerbie are investigating a number of housebreakings which took place on Sunday, December 20," Dumfries and Galloway police said in a statement. Pan Am flight 103 was blown out of the sky by a terrorist bomb on December 21, 1988, killing all 259 people on board and 11 on the ground in the sleepy border town of Lockerbie. Police said articles of jewellery were amongst the items taken and asked the public to report any offers of jewellery. Some 50 foreign visitors, mostly Americans, went to Lockerbie to spend the anniversary of the 1988 disaster with the local people who have become their staunch friends. Of the 270 dead, 189 were from the United States.
