Jerusalem ( CNN ) A day after flames scorched a West Bank mosque , a Jerusalem seminary belonging to the Greek Orthodox Church was torched and defaced Thursday -- an act police suspect is the work of radical right-wing Israelis . Both buildings were defaced with anti-Arab and anti-Christian slurs , including graffiti maligning Jesus on the seminary , said police spokeswoman Luba Samri . And in each case , there was writing in Hebrew referring to the `` redemption of Zion '' and `` revenge . '' The acts drew strong condemnation . `` There is no room for such deplorable activity in Jerusalem , '' Mayor Nir Barkat said Thursday . `` We must eradicate this behavior and bring those responsible to justice . '' Palestine Liberation Organization official Hanan Ashrawi called the acts `` hate crimes ( that ) constitute a flagrant attack on all Palestinians , whether Muslim or Christian . '' `` These are not isolated incidents , but rather they fit a longstanding pattern of deliberate provocation , extremism and violence , and are a vicious assault on all Palestinians and their holy sites , '' Ashrawi said . `` The recent events indicate that a holy war is already being waged against the Palestinian Muslim and Christian population . '' The incident at the mosque may be a `` price tag '' attack -- a term used by radical Israeli settlers to denote reprisal attacks against Palestinians in response to moves by the Israeli government to evacuate illegal West Bank outposts -- according to officials . In fact , video from the West Bank shows two letters that translate to PT , for `` price tag . '' And authorities suspect a Jewish nationalist motive for what happened at the Greek Orthodox seminary . Samri , the Israeli police spokeswoman , said that firefighters managed to douse the fire in that building 's restroom and showers before anyone was injured . But not much more is known than that . Shortly after the incident , a Jerusalem district court issued a gag order that covered all details of the investigation and anything that identifies suspects . CNN 's Michael Schwartz reported from Israel , and CNN 's Greg Botelho wrote from Atlanta .
