Palestinian Prime Minister Rami Hamdallah cancelled his visit to the Gaza Strip on Saturday to mark the anniversary of the death of Palestinian president and Fatah leader Yasser Arafat, Ma'an News Agency reported.
Senior Fatah officials Azam al-Ahmad and Hussien El-Shikh also dropped their Gaza visit.
The agency did not give any reasons for the cancelled visit, but a series of small explosions targeted the homes and vehicles of officials from Fatah movement in Gaza.
Hamas condemned the explosions as a "criminal" act and ordered those who carried them out to be brought to justice.
