A telecommunications pole fell and crushed two girls to death in the northern province of Phu Tho Saturday.
Nguyen Thi Linh, 16, and Phan Thi Kim Oanh, 10, had taken shelter from the sun under a tree while grazing their cattle when the concrete pole around six meters high fell on them.
The girls died on the way to hospital, said Hoang Xuan Le, a commune official.
Authorities are investigating the cause of the accident. The name of the telcom firm which owns the pole has not been released.
