Gaza City: A bomb blew up the car of an official with the Palestinian Islamist movement Hamas in Gaza, the second such attack in recent weeks, a security source said on Saturday.
The blast, which occurred last night but caused no casualties, comes as political tensions mount in the Palestinian territory.
"Police have opened an investigation after a makeshift bomb blew up the car of Sheikh Sami Hams in Nuseirat refugee camp" south of Gaza City, a security official told AFP on condition of anonymity.
The vehicle had been parked outside and was completely destroyed, according to witnesses.
It was the latest in a series of unclaimed attacks in Gaza.
On January 20, a bomb struck the car of the chief financial officer in the Hamas military police outside his home.
Analysts say such attacks indicate the gradual loss of control of Hamas over the enclave since it fought a 50-day war with Israel last year, since when radicals have become increasingly active.
