In his last speech to parliament before Christmas, British Prime Minister David Cameron on Wednesday (December 17) condemned the atrocities that took place in Australia and Pakistan in recent days.

"I'm sure the whole House will join me in condemning the outrages that have shocked the world in recent days. The siege of a cafe in Sydney ended in tragedy but was accompanied by heroism so typical of that great nation, and we all grieved with Australians today," Cameron told Parliament.

Three people were killed, including hostage-taker Man Haron Monis, when police stormed a Sydney cafe early on Tuesday (December 16) morning to free terrified hostages held at gunpoint for 16 hours.
