What? Although security in Beijing is at an all-time high with the country's 60th anniversary less than a week away, three men wielding long knives went on a rampage, killing at least two and injuring more than a dozen. Onlookers eventually threw stones and wooden boards at them, managing to catch one of the attackers. Who? One assailant was named as Zhang Jianfei , 46, from the northeastern city of Jilin . In another attack, a Frenchwoman suffered minor injuries after being slashed by a 40-year-old man. When? The first attack took place just before 7pm last Thursday, the night before a highly sensitive final rehearsal for the October 1 parade which will showcase the country's growing military power. The attack on the Frenchwoman happened the following Saturday. Where? The attack took place a few hundred metres away from Tiananmen Square in the Dashilan shopping area in Qianmen, southwest of the square. It is famous for housing some of the city's oldest shops. Why? Unofficial reports say the 40-year-old Saturday attacker was disillusioned and jobless. Beijing officials are wary of further incidents in the run-up to the October 1 National Day celebrations. They are worried about protesters and terrorists. How? How have the attacks affected life in the capital? A temporary ban on the sale of long knives has been put into place.
