(UPDATE) COLLATERAL DAMAGE: Thirty-one children have been killed so far amid the government's war on drugs, a non-government organization said Thursday.

The fatalities, all below 18 years old, were slain between July 1, 2016 and January 31, 2017, according to the Children's Legal Rights and Development Center (CLRDC).

"Mayroon tayong mga bata na they were really targeted... They were not really spared on this war on drugs," CLRDC executive director Rowena Legaspi said.

The youngest of the victims, she said, was a 4-year-old girl.

The CLRDC also monitored the cases of 3 children who suffered severe trauma and fear after surviving a drug-related attack.

The group said the numbers can be higher, assuming that there are cases yet to be reported.

Legaspi appealed to authorities to "spare the children" during anti-drug operations.

She said authorities must also verify any information about the involvement of minors in the drug trade and "respect the right of the accused" in confronting the child. -- Report from Sherrie Ann Torres, ABS-CBN News
