A rocket fired from the Gaza Strip between Sunday night and Monday morning struck southern Israel but did not cause any casualties or damage, an army spokesman said.

The rocket exploded in a field, and marked the third such attack from the Gaza Strip, controlled by the Islamist movement Hamas, since Friday.

Israeli police said Sunday they had arrested 39 Palestinians in the West Bank and east Jerusalem after days of protest and clashes over the flashpoint al-Aqsa mosque compound.

Palestinians clashed Friday with Israeli security forces in Jerusalem and several cities in the occupied West Bank, in a "day of rage" to protest an increase in Jewish visitors to Islam's third-holiest site.

Two rockets were fired into southern Israel by Palestinian militants in Gaza on Friday, causing no casualties but triggering a series of Israeli air raids.

No one was hurt in either of the attacks. One of the rockets hit a parked bus in the town of Sderot, while the Israeli army said the second was destroyed by its "Iron Dome" defense system over the town of Ashkelon.

The U.N. Security Council appealed for calm and restraint Thursday after three days of clashes this week at Jerusalem's Al-Aqsa mosque compound between Israeli police and Muslim protesters.

In a unanimous declaration, the 15-member panel also expressed its "grave concern" and called for maintaining the rules governing the sensitive site seen as holy by both Muslims and Jews.  

Israel has lashed out at a boycott of its products by the Icelandic capital's city council over the occupation of Palestinian territory, describing it as a "volcano of hatred".

Reykjavik's council on Tuesday approved a motion to halt the city's purchase of Israeli products until the occupation ends.

Prime Minister Benjamin Netanyahu will travel to Russia next week for talks with President Vladimir Putin on Moscow's military support for the Damascus regime and "threats" facing Israel, his office said Wednesday.

Netanyahu will speak about "the deployment of Russian military forces in Syria," a statement said.

Israel reinstated the detention without trial on Wednesday of Palestinian detainee Mohammed Allan, whose recent two-month hunger strike brought him near death and increased tensions in the occupied West Bank.

"Mohammed Allan, whose condition has improved, was arrested this morning by police at the hospital in Ashkelon," police spokeswoman Luba Samri said in a statement. 

Israeli Prime Minister Benjamin Netanyahu on Wednesday announced a toughening of the penalties for stone throwers following a third day of clashes in and around Jerusalem's flashpoint Al-Aqsa mosque compound.

Young Palestinian demonstrators threw stones at Israeli police who had entered the compound in large numbers and responded with stun grenades in fresh clashes Tuesday despite international calls for calm.

The EU warned Tuesday against any "provocation" at Jerusalem's al-Aqsa mosque compound as Palestinians and Israeli security forces clashed for a third day.

"The reported violence and escalation (at the site) constitute a provocation and incitement" ahead of important Jewish and Muslim holy days, European Commission spokeswoman Maja Kocijancic told reporters in Brussels.

Palestinians and Israeli security forces clashed in Jerusalem's flashpoint Al-Aqsa mosque compound and the surrounding Old City for a third straight day on Tuesday despite international calls for calm.

Young demonstrators gathered around the mosque threw stones at police who had entered the compound in large numbers and responded with stun grenades, an AFP journalist said.
