Three people were killed and 79 injured when attackers used knives and detonated explosives at a railway station in China.
The blasts took place in Urumqi in the Xinjiang region yesterday as president Xi Jinping completed a tour of the region, the BBC reported.
The Beijing government blames the violence on separatists from the mainly Muslim Uighur minority.
The incident follows an attack on Kunming station, in southern China, in March – also blamed on Uighurs – in which 29 people died.
Xinjiang has also seen a series of violent attacks in the past year.
Xi’s visit to the western Xinjiang region was the first since he became president in 2012.
“The battle to combat violence and terrorism will not allow even a moment of slackness, and decisive actions must be taken to resolutely suppress the terrorists’ rampant momentum,” Xinhua news agency quoted him as saying after the attack.
Xi said it was essential to “deeply understand Xinjiang separatism”.
