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. The explosion on Friday evening hit a canal that sends water to Kosovo's two coal-fired power plants - accounting for most of the country's power production.

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

Kosovo's Interior minister Xhelal Svecla said Saturday that police had arrested eight people after an explosion hit a canal that sends water to its two main power plants, an incident Pristina labeled a "terrorist act" by neighboring Serbia.
