A spokesperson for the Barzilai Medical Center says the Ashkelon hospital has treated 26 casualties relating to the ongoing violence.
The hospital says one person is in serious condition and one patient is classified as moderate.
In addition, 17 people were lightly wounded and seven received treatment for anxiety.
The hospital says the wounded include four members of one family and five children in total.
Palestinian terror groups in the Gaza Strip fired a massive barrage of rockets at Ashkelon at dawn. Seven Israelis were wounded in that attack, four of them members of the same family: parents in their 40s, an 8-year-old and an 11-year old.
