March 27 (Reuters) - The UK's FTSE 100 edged lower on Friday as uncertainty around de-escalation of the Middle East conflict persisted, though the index clung to slim weekly gains.
U.S. President Donald Trump extended his deadline to 8 p.m. ET on April 6 (0000 GMT on April 7) for Iran to reopen the Strait of Hormuz or face the destruction of its energy facilities, after Tehran rejected Washington's 15-point proposal to end the war.
The blue-chip FTSE 100 index closed 0.05% down, while the midcap FTSE 250 fell 1.5% and logged a weekly loss of over 1.7%. However, both indexes were on track for steep monthly losses.
