Two Arabs from Palestinian Authority enclaves were arrested trying to smuggle four pipe bombs, an improvised gun, and a large amount of ammunition into Israel on Tuesday.

Two Arab men in their 20s aroused the suspicion of Border Police officers at the Tapuach Junction, who detained and searched the pair.

Upon finding the weapons in their bags, Border Police called sappers were called to dispose of the devices. The pair were arrested and handed over to security offcials for questioning.

Such arrests have become commonplace as northern Samaria increasingly becomes a hub for the Hamas and Islamic Jihad terror organizations.

January 8: Border Police arrest two men carrying 12 pipe bombs and a combat knife at a checkpoint near Shechem in northern Samaria.

Last August the GSS cracked a network of Hamas terror cells in Judea and Samaria, each of which was in various stages of planning for attacks on Israelis.

One of the cells was behind the 23 March 2011 bus bombing in central Jerusalem that killed 1 and wounded 47.

Also, in late January 2012, the GSS and Israel Police foiled a shooting attack planned by an Israeli Arab in collaboration with an Islamic Jihad terror cell from Tulkarem in northern Samaria.
