Large rocket fragments fell near some of Jerusalem's holiest sites on Monday, raising concerns that Iran may now be targeting the city, The Telegraph reports.

In Jerusalem's Old City, a large piece of rocket landed in a narrow alley next to the Church of the Holy Sepulchre, built on the site where Christ is believed to have been crucified.

Police also cordoned off a small section of the Al-Aqsa Mosque compound — the third holiest site in Islam — after small fragments appeared on the grounds.

Debris also fell near the Knesset in the west of the city, close to Benjamin Netanyahu's office, while the rear section of a rocket pierced the roof of a house in Silwan, in East Jerusalem, a Palestinian-populated neighborhood.

It is unknown whether the rockets were aimed directly at the city or intercepted mid-flight on their way to another target. Nevertheless, several salvos have been observed that appear to have been aimed at the Israeli capital.

It had previously been assumed that Tehran would not attack Jerusalem due to the risk of damaging Islamic holy sites. However, reports emerged Monday that the government is placing mobile bomb shelters across the city — small above-ground concrete structures normally found near Gaza and in northern Israel.
