In a fresh move, the Israeli armed forces have kidnapped thirteen Palestinians during pre-dawn raids in various parts of the West Bank, the military says.

The operation was carried out Tuesday morning during night and dawn operations in the West Bank cities of Ramallah and Tulkarem.

The campaign came just days after Israeli troops kidnapped 11 Palestinians again in overnight operations carried out in the same areas of the West Bank. Over the last 10 days, Israeli forces have kidnapped at least 50 Palestinians in the West Bank.

Palestinians residing in the West Bank fall victim to overnight kidnapping operations on a regular basis despite a security agreement between Israel and the Palestinian National Authority.

According to the agreement, the PA is in charge of security in the West Bank and Israeli service members have no authority in the region.

Palestinians claim that Israel has kidnapped close to 2,400 Gazan citizens from the West Bank and surrounding areas since the start of 2009.

More than 11,500 Palestinians -- including women and children -- imprisoned by Israel are suffering under harsh conditions in detention facilities.
