The Palestinian Authority has held Hamas responsible for an explosion near the motorcade of Palestinian Prime Minister Rami Hamdallah during a visit to Gaza.
Mr Hamdallah and other senior officials were not hurt although there were reports of six injuries as a result of what the PA branded a deliberate assassination attempt.
The incident came amid a fragile truce between Hamas and Fatah, the other main Palestinian faction that controls the PA.
The explosion occurred shortly after 10 o’clock on Tuesday morning as Mr Hamdallah’s convoy entered the Gaza Strip from Israel through the Erez crossing.
