The Israeli occupation army said it struck militant targets in Gaza early on Sunday in response to continued launches of explosives-laden balloons out of the Hamas-run territory.
There were no immediate reports of casualties on either side. But the violence comes at a time when Gaza is struggling with a worsening economic crisis and a new outbreak of the coronavirus.
Hamas-linked groups have launched a wave of incendiary balloons into Israel in recent weeks, torching wide swaths of farmland. Israel has responded with airstrikes and other attacks.
The occupation army said Sunday's tank fire struck Hamas ``military posts'' in southern Gaza, without elaborating.
Hamas is pressing Israel to ease its blockade on Gaza and allow large-scale development projects. Egypt is trying to shore up a cease-fire.
Those efforts have grown more urgent in recent days as authorities in Gaza have detected the first cases of local transmission of the coronavirus. Hamas has imposed a lockdown in the coastal territory bordering Israel and Egypt, which is home to 2 million Palestinians.
Israel imposed a blockade on Gaza after Hamas seized power from rival Palestinian forces in 2007. Israel says the blockade is needed to keep Hamas from building up its arsenal, but critics view it as a form of collective punishment. Israel and Hamas have fought three wars and several smaller battles since the closure was imposed.
The restrictions have pushed the local economy to the brink of collapse, and years of war and isolation have left the health care system ill-equipped to cope with a major outbreak.
In response to the recent attacks, Israel closed Gaza's sole commercial crossing, forcing its only power station to shut down for lack of fuel and leaving Gazans with just a few hours of electricity a day. Israel has also closed the coastal territory's fishing zone.
The U.N.'s Mideast envoy, Nickolay Mladenov, last week warned the situation is ``rapidly deteriorating.''
