Egypt opened its border crossing with the Gaza Strip on Thursday for the second time in two months to allow medical aid and Palestinians to enter the coastal territory. More than 40 trucks carrying medicine and mineral water have crossed into Gaza so far, border official Ghazi Hamad said. He said that 120 Palestinians who were stranded in Egypt were also able to cross. Egypt has largely kept the crossing closed since the Islamic group Hamas took over the Gaza Strip in June 2007. Egypt, which has waged its own battle with Islamic militants at home, is wary of Hamas' rule in the neighboring territory.
