The Israeli army "foiled attempted stabbing attack by Palestinian at the Tulkarm checkpoint. Assailant was detained on the spot. No injuries reported," Israeli army spokesman Peter Lerner tweeted.
Tension has run high in the region since late October, when Israel briefly closed the flashpoint Al-Aqsa Mosque compound in occupied East Jerusalem after an extremist rabbi was shot and injured by a Palestinian man in West Jerusalem.
The shooting suspect was subsequently killed by Israeli forces in a raid on his East Jerusalem home.
Further aggravating the situation, a handful of Israeli MPs and scores of Jewish settlers have forced their way into the mosque complex in recent weeks, drawing the ire of Muslim worshippers and official condemnation from Arab and Muslim countries.
Since then, several Israelis have been killed and injured in a spate of attacks by Palestinians – both inside Israel and in the occupied territories.
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 Jewish temples in ancient times.
