Israel said Sunday it was suspending the entry of aid into Gaza, where both Israel and Palestinian sources reported Israeli military strikes as Hamas alleged a "coup" against a six-week old truce.The health ministry in Hamas-run Gaza reported at least four killed and six wounded in Israeli attacks.

Hamas accused Israel of trying to derail the cease-fire agreement hours after its first phase ended. It called the decision to cut off aid “cheap extortion, a war crime and a blatant attack” on the truce, which took hold in January after more than a year of negotiations. Both sides stopped short of saying the cease-fire had ended.
