GAZA CITY (AFP) - Israeli aircraft bombed a house in the Gaza Strip on Thursday in the first strike on the Hamas-ruled enclave in more than a month, the army and witnesses said. No casualties were reported in the strike in the Maghazi refugee camp in the centre of the densely-populated Palestinian territory, the witnesses said. An Israeli army spokesoman confirmed it had carried out a raid, without providing further details. The raid came one day after Gaza militants fired a rocket against southern Israel for the first time in 10 days, also causing no injuries. Both Israel and the Palestinian movement Hamas have failed to observe tenuous ceasefires they announced on January 18 that ended a devastating 22-day war by the Jewish state on the impoverished territory. Meanwhile, hundreds of people in Hamas-run Gaza on Thursday called for the release of prisoners in Israeli jails as they held a rally ahead of Palestinian Prisoner Day. Freedom for prisoners chanted the demonstrators as they marched in downtown Gaza City, many of them holding posters of loved ones held in Israeli jails. In the occupied West Bank city of Bethlehem, about 500 people gathered for a similar rally at Manger Square demanding the release of Palestinians held in Israeli jails. Palestinians will on Friday mark Prisoner Day, during which demonstrations are held across the occupied West Bank and the Gaza Strip to call for the release of their compatriots held by Israel. Israel currently holds some 11,000 Palestinian prisoners. Meanwhile, police beefed up security in Jerusalems Old City on Thursday following reports that Jewish extremists planned to rally on the Al-Aqsa Mosque compound as Muslims holds prayers there. Police sealed off the only access to the compound that non-Muslims are allowed to use. We have orders not to allow anyone in, an officer said at the gate, which overlooks the Wailing Wall, considered by Jews to be their holiest site. Access to the compound, which houses the Al-Aqsa mosque, was restricted to Muslims with Israeli IDs, aged at least 50 for men and of any age for women. A heavy police presence was evident throughout the Old City. Over recent days, Jewish extremists have urged Jews to gather at the site, Israeli media reported. The Islamic Movement in Israel responded with a call on Muslims to rally in defence of Al-Aqsa Mosque.
