Hamas security forces arrested Palestinian President Mahmoud Abbas's top Fatah representatives in the Gaza
Strip today, stepping up a crackdown after a series of bombings in the coastal enclave, Fatah officials said.
Hamas security men detained Ibrahim Abu an-Naja and Zakaria al-Agha, who were appointed by Mr Abbas to oversee Fatah in the Gaza Strip after Hamas Islamists seized control a year ago.
Hamas forces also arrested three local governors who were appointed by Mr Abbas, Fatah officials said.
