Gaza's ruling Hamas movement and the Islamic Jihad group say they fired rockets at Israel in response to an air strike that injured 10 people.
"In response to the injury of civilians in the most recent strike on Rafah, the Qassam Brigades and the al-Quds Brigades fired a number of rockets at enemy military positions," Hamas's Ezzedine al-Qassam Brigades armed wing said in a statement.
Israel's police spokesperson Luba Samri said on Monday that a barrage of more than 20 rockets hit Israel early on Monday, causing very light damage and no injuries.
The remains of "19 rockets were found in the Ofakim area, specifically near the Eshkol regional council. All rockets landed in open areas, and one home was damaged by shrapnel," she said.
In addition, "three rockets were found in the Kerem Shalom area, they caused no injuries or damage," Samri said.
The rocket fire came after an Israeli airstrike on the southern Gaza city of Rafah early on Sunday evening.
The strike targeted two men belonging to a Salafist militant group, Israel's military said, accusing the men of being involved in planning attacks on Israelis.
The men were critically wounded in the strike, which also injured eight others, including children.
On Monday morning, Ashraf al-Qidra, spokesperson for the Hamas health ministry in Gaza, said that tank shelling east of the Gaza city of Khan Yunis had injured three people, including one in a serious condition. – Sapa-AFP
