BEIJING, May 6 -- Chinese authorities will launch special operations against terrorism, said a senior security official here Tuesday.

Law enforcement agencies will fully implement the leadership's arrangement on counterterrorism, said Meng Jianzhu, head of the Commission for Political and Legal Affairs of the Communist Party of China Central Committee, at a meeting of officials from law enforcement and judicial departments.

Meng vowed that the authorities will hit terrorists hard. Law enforcement agencies and judicial departments will deploy new technologies to detect and remove security threats. They are urged to improve their relations with the public and win their support, especially on Internet.

Meng also asked the officials to exercise their power in line with protocols and laws instead of abusing it.

Three people were killed and 79 injured in an attack at a railway station in Urumqi, capital of northwest China's Xinjiang Uygur Autonomous Region, on April 30, and on March 1 assailants killed 29 civilians and injured another 143 at a railway station in the southwestern city of Kunming. The two incidents were confirmed as terrorist attacks.

On Tuesday morning, a male suspect carrying a knife attacked people at a railway station in the southern Chinese metropolis of Guangzhou. The nature of this attack has yet been confirmed.
