This is a criminal attack, a terrorist attack aimed at damaging important infrastructure for us, he said at a press conference late in the evening.
The EU condemns the attack and calls it a terrorist attack.
"It is a despicable act and a sabotage of Kosovo's infrastructure, which supplies large parts of Kosovo's population with drinking water and is a vital part of Kosovo's energy system", says EU's Foreign Minister Josep Borrell in a statement.
The US, France, and Turkey also condemn the attack. Serbia denies being behind the act.
