An Israeli solder looks on the site near the Israeli Gaza border, where a man was injured from a mortar shell fired from the Gaza Strip, Sunday, Aug. 3, 2014.
Israeli troops began observing a unilateral seven-hour humanitarian lull in most of the Gaza Strip from 0700 GMT on Monday.
But Hamas, the de facto rulers of Gaza, said they would not be reciprocating the lull and warned people "to take the utmost caution" when venturing out.
The army said the temporary truce would take place everywhere except to the east of Rafah on the Egyptian border where troops were still present and clashes were ongoing.
