Jerusalem (AFP) -
Prime Minister Benjamin Netanyahu vowed Monday that Israel would not bow to "knife terror" while four stabbings in Jerusalem gave no sign of Palestinian unrest slowing.
Frustrated Palestinian youths
have defied president Mahmud Abbas as well as an Israeli crackdown by
staging violent protests in annexed east Jerusalem and the occupied West
Bank, while 18 stabbings have targeted Jews since October 3.
There have been warnings of the risk of a full-blown uprising, or Palestinian intifada.
The stabbings have killed two Israelis and wounded about 20, including a 13-year-old critically injured on Monday.
Referring
to past uprisings, Netanyahu said Israel had overcome previous bombing
campaigns and "knife terror will not defeat us now".
But security forces have struggled to stop the stabbings, mostly committed by youths believed to be acting on their own.
In Monday's first stabbing, an
18-year-old Palestinian from east Jerusalem attacked a policeman at an
entrance to the Old City and was shot dead by officers.
The policeman's protective vest stopped the knife and he was unharmed.
Later,
a female attacker stabbed a policeman near the force's headquarters in
Jerusalem and was shot and wounded by the officer, police said.
In
another attack, two Palestinians stabbed two Israelis in the east
Jerusalem settlement of Pisgat Zeev, with one attacker, 17, killed and
the other, 13, shot and seriously wounded.
The
victims were both Jews, with a 13-year-old who was riding a bicycle
critically wounded and a 25-year-old seriously hurt, police said.
After nightfall an Arab man on a
bus entering Jerusalem stabbed an off-duty soldier and tried to grab
his weapon, lightly wounding him before being shot dead by police.
Palestinian
rights group Al-Haq accused Israel of "shooting to kill" Palestinian
attackers when they are surrounded by armed security personnel and no
longer pose a deadly threat.
"According
to international law, lethal force may not be used except when one or
more lives are in actual danger," said Al-Haq director Shawan Jabarin.
- Growing anger -
The
violence began on October 1, when an alleged Hamas cell shot dead a
Jewish settler couple in the West Bank in front of their children.
t followed repeated clashes at
Jerusalem's flashpoint Al-Aqsa mosque compound in September between
Israeli forces and Palestinian youths.
The
unrest has spread to the Gaza Strip, hit by three wars with Israel
since 2008. Clashes along the border left nine Palestinians dead from
Israeli fire on Friday and Saturday.
On
Monday evening, dozens of Gazans broke through the border fence and
briefly entered Israel before being pushed back by troops, Palestinian
witnesses said.
Medical officials said two men were injured by army fire.
Palestinian
frustration has mounted with efforts towards statehood at a standstill
and Israel's occupation continuing, and a recent poll found a majority
favouring an armed uprising in the absence of peace talks.
Funerals of Palestinians killed
during unrest or while allegedly carrying out attacks -- as well as
videos of the shootings -- have fed anger.
On
Monday, children with plastic guns mixed among hundreds of others who
carried the body of Ahmed Sharake, 13, during his funeral procession at
the turbulent Jalazone refugee camp.
He was killed on Sunday during clashes in Ramallah.
- More than 1,000 wounded -
Some 25 Palestinians have been killed amid the unrest, including alleged attackers.
Palestinians
have thrown stones and firebombs at Israeli forces, who have responded
with live fire, rubber bullets, tear gas and stun grenades.
The Red Crescent said Sunday that 1,021 Palestinians have been wounded by live fire and rubber bullets since October 3.
Palestine
Liberation Organisation secretary general Saeb Erekat lashed out at
Netanyahu, saying "executions" and harassment from Jewish settlers had
exacerbated the violence.
In Vienna, Palestinian foreign minister Riad al-Malki accused Israel of inciting the violence.
"Netanyahu
wants to instigate a third intifada. He wants to avoid problems that he
is facing in the political and diplomatic arena, where he has failed
miserably," Malki told AFP.
Netanyahu called on Abbas to stop what he called Palestinian incitement and to condemn attacks.
Both
Netanyahu and Abbas have sought to avoid an escalation, but frustrated
Palestinian youths have defied efforts to restore calm.
Israel also said Monday that YouTube had taken down Palestinian videos that the Jewish state considered to be "inciting murder".
Videos
of Palestinians stabbing Israelis or calling for such attacks as well
as footage of protesters throwing stones at Israeli soldiers have been
shared on the Internet, in addition to the shooting footage.
