Several blasts erupted in Kabul on Saturday, killing at least 19 people, according to Reuters, adding to this week's wave of violence in the Afghan capitol.

The Italian-run hospital in Kabul reported 19 people died in the blasts, while 16 of the wounded were brought to the hospital. Afghanistan's interior minister reported six people died in the attack and 87 were left wounded.

Saturday's blasts occurred at the funeral of the son of Afghanistan's deputy Senate speaker, Mohammad Alam Izadyar, who was killed Friday in deadly protests in which police opened fire into a crowd of demonstrators en route to the presidential palace.

Friday's protestors were demanding the resignation of top Afghan officials following Wednesday's car bomb explosion near the U.S. embassy that killed eight people and wounded 25 others. The attack was aimed at foreign troops.

The Islamic State in Iraq and Syria (ISIS) claimed responsibility. The Taliban, which has been frequently responsible for attacks in the region, has denied responsibility.

The slew of violence has increased tensions between Afghanistan's ethnic political groups.

President Ashraf Ghani condemned the recent wave of violence and called for national unity on Twitter on Saturday.

"The country is under attack," Ghani said. "We must be strong and united."
