French authorities have tightened security precautions at its embassies and missions abroad namely schools following announcement of the death of Al-Qaeda chief Osama Bin Laden. Prime Minister Francois Fillon, in remarks to France-2 Television, late on Monday, said the French Government had given instructions to the diplomatic and academic missions to tighten security measures in and around their premises. Death of Bin Laden does not mean the end of terrorism, he said, indicating at various and ongoing threats targeting French interests in some countries, he added, noting that the vigilance instructions were given in anticipation of possible retaliatory actions by Al-Qaeda or splinter groups loyal to the notorious organization. Justice has been served with the killing of the Al-Qaeda chief, he said, also stating that conditions across the Arab world have changed with rise of pro-democracy movements since the 2001 Sept. 11 attacks on the US.
