'We've seen and heard a number of explosions here in Gaza'
Israel says it has resumed air strikes in Gaza after Palestinian militants fired rockets following the end of a three-day truce on Friday morning.
The Israeli army called the renewed rocket attacks "unacceptable, intolerable and short-sighted".
Palestinian militant group Hamas, which controls Gaza, earlier rejected any extension of the truce, saying Israel had failed to meet its demands.
