The death toll from the Israeli air raids in Gaza since dawn has risen from nine to 13, medical sources told Al Jazeera.

Among those killed in the attacks was journalist Helmi al-Faqawi. He was in a tent sheltering journalists near Nasser Hospital in Khan Younis when the Israeli forces struck.

They have pledged more attacks after Hamas’s armed wing Qassam Brigades launched at least 10 rockets into Israel.
