The IDF has intensified Operation 'Brothers' Keeper,' IDF officials reported Sunday morning, and have searched in 1,400 different sites total since last week in an effort to locate three kidnapped teenagers.
As of Sunday, the IDF has shifted its focus to the northwest of Hevron, for a period of approximately 48 hours, they said.
Over 350 Palestinian Arabs - mostly Hamas terrorists - have been arrested since the operation began last Friday, the IDF announced Sunday.
Saturday night, nine more suspects were apprehended in Judea and Samaria and the Jordan Valley; one Palestinian Arab was accidentally killed in Shechem (Nablus) after approaching IDF forces.
The suspect began to approach a base "in a threatening manner," an IDF spokesman told AFP Sunday morning.
When he failed to respond to warning shots fired in the air, they fired towards him.
"Initial inquiry suggests that the suspect was mentally unstable," a military statement said.
Elsewhere, troops shot dead 30-year-old Mohammed Tarifi during clashes in central Ramallah, in an incident which also saw another five wounded, Palestinian medics said Sunday.
There was no immediate comment from the army.
Shortly after the soldiers left, Palestinians began hurling rocks at a local police station in the city and smashed the windows of two police cars, an AFP correspondent said.
