The IDF arrested 30 wanted Palestinians in the West Bank before dawn on Thursday, two of whom were former prisoners released in the Gilad Schalit prisoner swap.
IDF troops combed 100 homes and public institutions affiliated with Hamas, mostly in the Hebron area, according to Israel Radio.
A military source told Israel Radio that the Palestinians were showing more signs of restlessness and resistance to IDF operations on the ground. Explosive devices were hurled at IDF forces operating in the Jenin refugee camp. No injuries were reported and arrests were made.
Since the start of operations in the wake of the kidnapping of three teens, 280 Palestinians have been arrested, 53 of whom were freed in the Schalit transaction.
