by Emad Drimly, Saud Abu Ramadan GAZA, Sept. 10 (Xinhua) -- The Gaza Strip people on Friday celebrated the first day of the three-day Lesser Bairam, or Eid al- Fitr holiday, with joy, yet mixed with caution and concern of an escalation of tension and violence with the Israeli army. On Thursday night, Israeli war jets carried out five successive air strikes on Hamas security installations and smuggling tunnels under the borderline between Egypt and southern Gaza Strip, wounding at least one Palestinian and causing severe damages to the facilities. An Israeli army spokesman told Israel Radio that the air strikes targeted weapon stores belonging to Gaza militants in response to a series of homemade rocket attacks carried out by the militants on southern Israel. On Friday morning, the spokesman announced that another homemade rocket was fired from the Hamas-controlled Gaza Strip at southern Israel causing no injuries, but the act itself has kept the door open for further escalation of violence on the ground. Amid this atmosphere, tens of thousands of Palestinians made the prayers of the Lesser Bairam, or Eid al-Fitr, in mosques all over the costal enclave. After the prayers, Gaza Strip residents spent the day visiting and exchanging greetings with their relatives, friends and families. A few children and their families visited parks and entertainment places in Gaza City in an attempt to express happiness for the Lesser Bairam, or Eid al-Fitr, and also to look for special entertainment in such occasions. Local non-government organizations held on Friday afternoon simple celebrations to amuse the children in several public squares and areas all over the enclave, showing entertainment videos and films. Most of Gaza families cook in the first day of the Eid the traditional salty fish or 'Feseikh'. The Gazans have had such kind of food for breakfast for ages to compensate the salt they lost during the 30-day month of Ramadan in which they fast around 15 hours a day. Cemeteries are also crowded with people visiting the graves of their beloved people who passed away either during Israeli army offensives on the Gaza Strip or died of normal diseases or accidents. Families of the prisoners in Israeli jails also visit the International Committee of the Red Cross (ICRC) in Gaza. They demonstrated in front of the ICRC, calling for the immediate release of their children imprisoned in Israeli jails. According to the official figures, there are around 700 prisoners from the Gaza Strip imprisoned in Israeli jails now and their families have been barred to visit them for four years. Meanwhile, this year's Eid is still under Israeli blockade, which was imposed in June 2007 right after Islamic Hamas movement seized control of the enclave by force during internal fighting with President Abbas' Fatah party. Israel decided in June to ease the blockade and allow more items, products and goods into the enclave following the Israeli naval commandos attack on the Gaza aid flotilla in May 31, where nine activists of Turkish nationalities were killed and dozens wounded. The Lesser Bairam, or Eid al-Fitr, also came as the Palestinians are still divided amid mounting rifts between Hamas, which rules the Gaza Strip, and Fatah, which rules the West Bank. The Gaza population is still waiting for a comprehensive reconciliation.
