Five people were injured in an explosion at Shanghai Pudong International Airport Sunday afternoon, authorities said. 
The explosion happened when a man threw a homemade explosive to a check-in counter in Terminal 2, the Shanghai Municipal Public Security Bureau said in a statement Sunday evening. 
After the explosion, the man took a knife from his backpack, cut his neck and then fell to the ground, police said. 
The suspect, now in critical condition, was under emergency treatment. 
Four passengers, including a Philippine national, were slightly injured by shards of glass and were being treated in hospital. 
A few flights were affected as their passengers were scheduled to check in at the explosion site, but the airport is now in normal operation.
