The UN said on Monday it had suspended its building projects in the Gaza Strip due to a shortage of supplies following Hamas’s violent seizure of the Palestinian territory last month. “Some 93 million dollars-worth of projects are on hold because cement and other building supplies have run out,” John Ging, the director of the United Nations agency for Palestinian refugees (UNRWA) in Gaza, said in a statement. UNRWA warned in the wake of the Islamist group’s seizure of Gaza on June 15 that aid flowing into the impoverished territory, mainly from Israel, was not enough to prevent a humanitarian crisis.
