Samurai sword attack outside Taiwan presidential office

A samurai sword-wielding attacker carrying the national flag of China slashed a military police guard outside Taiwan's presidential office Friday, authorities said.The presidential office in the centre of the capital Taipei is the headquarters of Taiwan's Beijing-sceptic President Tsai Ing-wen.Relations with Chinese authorities have deteriorated since she took office last year as she has refused to agree to Beijing's stance that Taiwan is part of "one China".
