Awwal 28, 1432 H/March 3, 2011, SPA -- All banks in the Gaza Strip have temporarily shut down after gunmen forced a local branch to cash some $500,000 in stolen checks, AP reported. Gazan bankers say the checks were confiscated from a branch of the Palestine Investment Fund _ which is run by the rival Palestinian government in the West Bank. Bankers say gunmen forced the fund's office manager to sign the checks, and bank tellers to cash them, though the account didn't contain enough money. The bankers say men affiliated with the ruling Hamas movement stole cash in similar incidents this year. They suspect the gunmen in Wednesday's incident were also Hamas-associated. Hamas police were not available for comment. The Palestine Monetary Authority _ which regulates Palestinian banks _ closed all Gaza branches Thursday. They are to reopen Sunday. -- SPA
