Many warned that truce is fragile, and progress must be done slowly while observing that the truce and quiet are kept. On 9–10 February night, a barrage of 25–50 Qassam rockets and mortar shells hit Neve Dekalim settlement, and another barrage hit at noon. Hamas said it was in retaliation for an attack in which one Palestinian was killed near an Israeli settlement. As a response to the mortar attack, Abbas ordered the Palestinian security forces to stop such attacks in the future. He also fired senior commanders in the Palestinian security apparatus. On 10 February, Israeli security forces arrested Maharan Omar Shucat Abu Hamis, a Palestinian resident of Nablus, who was about to launch a bus suicide attack in the French Hill in Jerusalem.
