Israeli military exercises of this level have not been conducted in ten years, Israeli newspaper Maariv quoted unnamed Israeli military sources as saying.
The sources did not clarify the nature of the drills, nor did they indicate their duration or how many troops are participating in them.
According to the sources, the main objective of the drills is to raise the efficiency levels of the Israeli troops in anticipation for any scenario.
Meanwhile, Israeli security sources said that attacks in the West Bank during 2014 rose by 33 percent compared to 2013.
The sources said that developments in Jerusalem and the Al-Aqsa Mosque compound, as well as in Arab towns and villages in Israel have led to the deterioration of security conditions in the West Bank.
Tension has mounted in the occupied West Bank ever since the kidnap and murder of three Israeli settlers last summer and the subsequent abduction and murder of a Palestinian teenager.
Both incidents preceded a devastating Israeli military onslaught on the Gaza Strip in July and August of last year which left over 2,160 Palestinians dead – the vast majority of them civilians – and some 11,000 injured.
The rising tensions in the West Bank even further escalated in late October when Israel briefly closed occupied East Jerusalem's flashpoint Al-Aqsa Mosque compound after an extremist rabbi was shot and injured by a Palestinian man in West Jerusalem.
For Muslims, Al-Aqsa represents the world's third holiest site. Jews, for their part, refer to the area as the "Temple Mount," claiming it was the site of two prominent Jewish temples in ancient time
