A special unit of undercover IDF troops arrested four Palestinians in Qalqilyah overnight for the murder of Israeli doctor Daniel Yaakovi last week.

One of the four detainees is a member of the Al-Aqsa Martyrs Brigades, the military wing of Palestinian Authority Chairman Mahmoud Abbas' Fatah movement, and the other three are his assistants.

The militant group said Saturday that it had killed the 59-year-old doctor, a resident of the Yikar settlement.

"He was killed because Israel has spared no Palestinian," Al-Aqsa said in a statement. "This is a message of fire - a burning message to the occupation. Killing, burning and fire."

Troops found a handgun in their possession, which was apparently used to kill Yaakovi.
