The IDF arrested 13 Palestinian Arab terrorists overnight, it announced Sunday, in light of increased tensions in Judea and Samaria. 

A military spokeswoman told AFP Sunday that the suspects - all wanted for "illegal activities" - were apprehended in Hevron and Bet-Lehem, as well as in two Arab settlements north of Ramallah. 

Security forces and IDF staff increased patrols in Judea and Samaria last week, after two Palestinian Arab anarchists were killed during violent clashes outside the Ofer Prison.

The clashes, in honor of anti-Israel hate-fest "Nakba Day," sparked heightened tensions in the region as Palestinian Arab media blamed Israel for "police brutality."

An investigation revealed that the two men had crossed a security fence before the IDF acted, shooting them with rubber bullets.
