A blast collapsed a tunnel under the Gaza Strip-Egypt border early Friday, trapping five men inside and killing at least one, Palestinians said. The Al Aqsa Martyrs' Brigades, an offshoot of Fatah movement, said the five were members.
On Thursday, gunmen killed a Fatah member in the Gaza Strip and a supporter of rival group Hamas was critically wounded in separate incidents.
Witnesses and medics said armed men opened fire on the Fatah member in the southern Gazan town of Rafah. The man later died of his wounds.
In the northern Gaza Strip town of Beit Lahia gunmen critically wounded a member of Hamas.
In a fresh attack later on Thursday, gunmen shot a police officer loyal to Fatah in his legs in Jabalya district, witnesses said. Fatah officials blamed Hamas gunmen for shooting the officer.
