Kabul, Afghanistan (CNN) -- Violence tore through Afghanistan on Saturday in three deadly insurgent attacks, authorities said.

The incident followed an earlier attack in Kunduz province, where a motorcycle bomb detonated in a market, killing at least 10 people, including three children in what the country's Interior Minister called an "un-Islamic and inhumane action." There were 18 people injured as well in the northern province.
ISAF denounced the strike and said insurgents are continuing "to engage in indiscriminate attacks which put Afghan civilians in harm's way" -- despite guidance from the Afghan Taliban leadership's to its fighters to avoid civilian casualties.
ISAF said that since the beginning of the month, "insurgents have engaged in at least 47 acts of indiscriminate violence" in civilian areas.
In Nangarhar province, located in the east, insurgents attacked an ISAF observation post at the Jalalabad airport, and six of the alleged attackers were killed by Afghan and foreign troops.
