Israel Removes Samaria Checkpoint to 'Relieve' PA Arabs
Israel ordered the removal of another security checkpoint Thursday morning as part of the "ongoing relief plan" being implemented in Judea and Samaria.
The IDF Spokesman said the move is meant to "significantly improve the freedom of movement and routine life of the Palestinian population in the Tulkarm region," and will allow free movement between the city and the rest of northern Samaria.
The removal of the checkpoint comes less than a day after U.S. Secretary of State Hillary Clinton left the region. The American official spent much of Wednesday in Ramallah, where she met with Palestinian Authority Chairman and Fatah leader Mahmoud Abbas, PA Prime Minister Salam Fayyad and various other PA officials.
Good measures are always answered with Arab's "good will" (to murder).
