Serbian President Aleksandar Vucic pledged on Sunday his country would help investigate after an explosion in Kosovo that disrupted water supplies and that the government there blamed on Belgrade.

Serbia's president has rejected any responsibility for a powerful explosion that temporarily cut water and power supplies to large swathes of neighboring Kosovo.

A blast on a canal vital to Kosovo's water and power supplies has sparked a war of words with Serbia, with fears it could further escalate tensions between the two Balkan nations.The explosion late Friday punched a hole in a canal providing water to hundreds of thousands of people and the cooling systems at two coal-fired power plants that generate most of Kosovo's electricity.
