Two Islamic Hamas movement's militants were killed early on Saturday in an Israeli airstrike on a car in the southern Gaza Strip city of Rafah, witnesses and medical sources said.

Medical sources said that an Israeli fighter jet struck a car in the town of Rafah and killed two people that were in it.

The sources said that since Thursday afternoon, 16 Palestinians were killed and 60 wounded, adding that on Thursday, five were killed and on Friday nine killed and early on Saturday two killed.

The tension in the Gaza Strip mounted on Thursday afternoon when Hamas militants fired a mortar shell from Gaza at southern Israel, where a school bus was hit and a 16-year-old Israeli teen was critically wounded.

On Thursday night, Hamas Ministry of Interior declared that after contacting the factions and the militant groups in the Gaza Strip, a ceasefire was agreed. However, Israel said it wasn't officially notified about the ceasefire.
