The UN agency for Palestinian refugees on Tuesday denied rumors its staff had vacated the Gaza Strip during Israel\'s latest offensive. UNRWA spokesman Adnan Abu Hasna said in a statement that employees did not leave Gaza on Israeli orders or because of escalating tensions earlier in March. UNRWA staff remain in Gaza and will not leave, Abu Hasna said, adding that the agency\'s employees were in the enclave to serve the people, particularly in difficult times. He noted that UNRWA\'s international employees who were on vacation when Israel\'s launched its December 2008 war on Gaza returned to the enclave during the offensive. UNRWA\'s regional headquarters are in Gaza and staff often travel, he added.
