Israel denied any responsibility for the blasts, and an Israeli army spokesman said he was unaware of any involvement in the incident.

Earlier on Tuesday, Israel launched an air strike on Hamas targets in Gaza. The Israeli army said the raid was in response to a mortar shell fired from the Gaza Strip towards Israeli territory.

Al-Jazeera correspondent in Gaza, Wael Dahdouh, said that the blasts targeted two police checkpoints in the southwest of Gaza City, which are unusual targets in the bombings and targets that usually occur in the Gaza Strip.

He added that there are conflicting accounts in Gaza between those who talk about an accident and those who confirm that it was a deliberate explosion, and some accuse Israel of responsibility, while others go to accuse others, in light of the uncertainty prevailing in the situation.
